- Accurate and non-invasive optical metrology of transparent objects is essential in a wide range of scientific and industrial applications, from fluid dynamics to biomedical imaging. In this work, a digital holography approach for temperature mapping is presented that leverages a double field of view (FOV) configuration combined with high spatial bandwidth utilization (SBU). By capturing a multiplexed hologram from two distinct objects in a single-shot, the system overcomes the limitations inherent to single-view holography, enabling a more comprehensive object information of temperature-induced refractive index variations. The method integrates double FOV digital holography with high SBU, allowing for the accurate surface profiling and mapping of complex optical path length changes caused by temperature gradients. The technique exhibits strong potential for applications in glass industry and microfluidic thermometry, convection analysis, and combustion diagnostics, where precise thermal field measurements are crucial. Overall, this study introduces an efficient holographic framework that advances the capabilities of non-contact measurement applications by integrating double FOV acquisition in a single-shot with enhanced spatial bandwidth exploitation. The approach sets the groundwork for real-time, volumetric thermal imaging and expanding the applicability of digital holography in both research and industrial settings.MDPI AG, May 2025
- Optical scanning holography (OSH) can measure three-dimensional (3D) fluorescence targets by recording incoherent holograms with two-dimensional Fresnel zone pattern (FZP) scanning and a single-pixel detector. However, the complexity of the optical setup has limited its applicability. Computational OSH (COSH) has been proposed as a solution to this problem and has shown to be feasible with optical applications such as ghost imaging or Hadamard transform single-pixel imaging. However, the problem with FZP’s scanning speed has limited its ability to visualize dynamic objects. In this study, dynamic objects were visualized using a high-speed digital micromirror device (DMD). In addition, a microscope based on COSH was constructed and then applied to capture moving images of dynamic objects behind dynamic scatterers. The experimental results show that the proposed method captures incoherent holograms with a frame rate of 1.387 Hz using a single-pixel detector. Moreover, numerical simulations indicate that the proposed method achieves imaging with a frame rate of approximately 28 Hz by using random sparse sampling and compressive sensing-based reconstruction.Optica Publishing Group, May 2025, Optics Express, 33(10) (10), 21903 - 21903[Refereed]Scientific journal
- A highly sensitive, rapid, and high-resolution method for wide-area microdefect inspection is essential in the semiconductor industry. Deep learning ghost imaging (DLGI) offers high sensitivity and fast measurement capabilities; however, its resolution is constrained by the illumination pattern. To address this limitation, we propose sub-pixel DLGI (SP-DLGI), which leverages illumination to enhance resolution. By utilizing a deep learning model, SP-DLGI predicts sub-pixel defect positions by analyzing subtle intensity variations induced by illumination blurring. Consequently, SP-DLGI enables rapid, high-sensitivity, and high-resolution imaging. Experimental results demonstrate that SP-DLGI effectively predicts defect positions at an 8K resolution.Optica Publishing Group, Apr. 2025, Applied Optics, 64(13) (13), 3724 - 3724[Refereed]Scientific journal
- In this work, a new framework of lensless Fourier transform multiplexed digital holography (LFTMDH) is proposed, leveraging the double field of view (FoV) in a single-shot recording. The proof-of-concept system with double FoV is realized by adopting a spatially multiplexing technique by inserting a cube beam splitter in the object path. The cube beam splitter divides the object beam into two FoVs with different object information. By carefully aligning and optimizing the orientation of the cube beam splitter, these two FoVs along with a spherical reference beam (generated at the object plane) are allowed to interfere with the active region of an image sensor, resulting in a multiplexed Fourier digital hologram. The object information (amplitude and phase) is obtained by applying a single Fourier transform to the recorded digital hologram, making the technique faster with the added benefit of double FoV, compared to its counterparts. The feasibility and advantages of the proposed system are demonstrated through experimental validation and comparative analysis with the existing system. The results indicate that the proposed system not only achieves double FoV imaging in a single-shot recording but also maintains spatial resolution in the reconstructed images. Its applications span various fields, such as biological microscopy, nondestructive testing, and optical metrology, where wider FoV is crucial.Optica Publishing Group, Mar. 2025, Optics Letters, 50(6) (6), 1909 - 1909[Refereed]Scientific journal
- The existing non-interferometric phase imaging methods are unable to retrieve quantitative phase up to microsecond temporal resolution due to the lack of a suitable parallel recording strategy. Therefore, we propose an ultra-high-speed non-interferometric method for phase and multi-plane imaging using partially coherent light sources. The method uses space division multiplexing to record two or more intensity images in parallel. Due to its ability to acquire images at desired distances, high-speed non-interferometric quantitative phase retrieval can be performed. Furthermore, due to its phase retrieval capability, numerical focusing can be achieved, allowing multiple axial plane images to be obtained from parallelly recorded images. The applicability of the proposed method is confirmed by imaging high-speed gas flow, where both the initial stage and the evolution of cavity formation can be visualized, as well as by imaging electric discharge, where the blocking of light by afterglow plasma can be observed. The developed imaging method can be applied to study phenomena with a wide range of speeds, from static to very fast, in various fields such as physics and life sciences, without the need for coherent light illumination.Optica Publishing Group, Mar. 2025, Optica, 12(3) (3), 350 - 350[Refereed]Scientific journal
- In recent years, the security of audio data has become paramount in terms of personal information, national security, and forensic evidence. However, most reported systems use digital algorithms and lack their implementation in the optical domain, which can provide better security due to the use of physical keys and high speed. In addition, recently developed phase-encoded audio encryption schemes in the optical domain have quality limitations due to precise wavefront measurement and control. Perfect experimental alignment to achieve good quality retrieved data is very challenging, due to which no optical implementation of voice security has been reported. This work introduces a robust audio encryption scheme using the polarization property of a light beam. Initially, one-dimensional (1D) audio combined with a random dataset acts as an encryption key and converts it to 1D cipher audio, which is transformed into a two-dimensional (2D) cipher-audio map. Subsequently, this is fragmented into several 2D segments, which are then encoded into the light beam using binary polarization states. An arbitrary sequence is maintained during encoding of the 2D segments into binary polarization states. The demonstrated technique is a non-interferometric method, and the decryption can be achieved through intensity recording only.AIP Publishing, Mar. 2025, APL Photonics, 10(3) (3)[Refereed]Scientific journal

- Optical scanning holography (OSH) is one of the single-pixel imaging (SPI) techniques. Although OSH can obtain an incoherent hologram using a single-pixel detector, OSH needs a complicated optical setup to generate Fresnel zone patterns (FZPs). Computational OSH (COSH) has been proposed to overcome the complexity of OSH by using a spatial light modulator (SLM). However, the measurement time of COSH is restricted by the refresh rate of an SLM for changing FZPs. While the number of measurements can be reduced by applying compressive sensing in conventional OSH, the scanning trajectory of FZPs is limited to the spiral manner because of the requirement of sequential scanning using galvo mirrors. The spiral scanning trajectory induces undesired artifacts in reconstructed images under sparse sampling conditions. If holograms can be randomly subsampled, these undesired artifacts can be reduced. In this paper, under COSH’s configuration, random sparse sampling of a hologram is proposed to overcome the problem of the limited trajectory of FZPs by discretely displaying FZPs on an SLM. In addition, compressive sensing is applied to reconstruct an object image from a randomly sampled hologram. The feasibility of the proposed method is confirmed numerically and experimentally. The experimental results indicate that the proposed method can identify the object even when the hologram is randomly subsampled with a sampling rate of 5%.Optica Publishing Group, Feb. 2025, Applied Optics, 64(7) (7), B102 - B102[Refereed]Scientific journal

- A transport of intensity equation (TIE) based three-dimensional (3D) fluorescence imaging using photon-counting detection was proposed for low light-level bioimaging applications. The number of photons required to achieve the quantitative phase measurement using the proposed system was investigated experimentally and numerically. Results show that the feasibility of reconstructing phase information with an average number of photons is greater than about 9 per pixel in our plant cells.Last, Optica Publishing Group, Nov. 2024, Optics Express, 32(23) (23), 42005 - 42005[Refereed]Scientific journal

- Most optical information processors deal with text or image data, and it is very difficult to deal experimentally with acoustic data. Therefore, optical advances that deal with acoustic data are highly desirable in this area. In particular, the development of a voice or acoustic-signal authentication technique using optical correlation can open a new line of research in the field of optical security and could also provide a tool for other applications where comparison of acoustic signals is required. Here, we report holographic acoustic-signal authentication by integrating the holographic microphone recording with optical correlation to meet some of the above requirements. The reported method avails the flexibility of 3D visualization of acoustic signals at sensitive locations and parallelism offered by an optical correlator/processor. We demonstrate text-dependent optical voice correlation that can determine the authenticity of acoustic signal by discarding or accepting it in accordance with the reference signal. The developed method has applications in security screening and industrial quality control.Optica Publishing Group, Sep. 2024, Photonics Research, 12(10) (10), 2104 - 2104[Refereed]Scientific journal

- Cholangiocarcinoma is one of the rarest yet most aggressive cancers that has a low 5-year survival rate (2% - 24%) and thus often requires an accurate and timely diagnosis. Hyperspectral Imaging (HSI) is a recently developed, promising spectroscopic-based non-invasive bioimaging technique that records a spatial image (x, y) together with wide spectral (λ) information. In this work, for the first time we propose to use a three-dimensional (3D)U-Net architecture for Hyperspectral microscopic imaging-based cholangiocarcinoma detection and classification. In addition to this architecture, we opted for a few preprocessing steps to achieve higher classification accuracy (CA) with minimal computational cost. Our results are compared with several standard unsupervised and supervised learning approaches to prove the efficacy of the proposed network and the preprocessing steps. For instance, we compared our results with state-of-the-art architectures, such as the Important-Aware Network (IANet), the Context Pyramid Fusion Network (CPFNet), and the semantic pixel-wise segmentation network (SegNet). We showed that our proposed architecture achieves an increased CA of 1.29% with the standard preprocessing step i.e., flat-field correction, and of 4.29% with our opted preprocessing steps.Optica Publishing Group, Jul. 2024, Optics Continuum, 3(8) (8), 1311 - 1311[Refereed]Scientific journal

- A three-dimensional (3D) fluorescent imaging method through a scattering medium has been presented. The proposed method combines digital phase conjugate reconstruction of the scattered light wave by the transport of intensity equation-based 3D fluorescent imaging to the position of scattering medium and followed phase retrieval method by Fresnel ping-pong algorithm. The effectiveness of the proposed method is experimentally verified by measuring the 3D distribution of fluorescent beads and tobacco-cultured cells through a thin diffuser. Compared to other methods, the reconstructed images show enhancement of the detailed structure of the objects blurred by the diffuser in a wide area. In the simulation, the proposed method is capable of recovering images degraded by scattering in the phase modulation range from 0 to 2π. The capability to identify the depth position is also presented.Last, Optica Publishing Group, Jun. 2024, Optics Express, 32(14) (14), 23989 - 23989[Refereed]Scientific journal

- Defect inspection is required in various fields, and many researchers have attempted deep-learning algorithms for inspections. Deep-learning algorithms have advantages in terms of accuracy and measurement time; however, the reliability of deep-learning outputs is problematic in precision measurements. This study demonstrates that iterative estimation using neighboring feature maps can evaluate the uncertainty of the outputs and shows that unconfident error predictions have higher uncertainties. In ghost imaging using deep learning, the experimental results show that removing outputs with higher uncertainties improves the accuracy by approximately 15.7%.Optica Publishing Group, May 2024, Applied Optics, 63(14) (14), 3736 - 3736[Refereed]Scientific journal
- Holographic techniques are indispensable tools for modern optical engineering. Over the past two decades, research about incoherent digital holography has continued to attract attention. Optical scanning holography (OSH) can obtain incoherent holograms using single-pixel detection and structured illumination with Fresnel zone patterns (FZPs). Particularly by changing the size of a detector, OSH can also obtain holograms under coherently illuminated conditions. Since 1979, OSH has continuously evolved. According to the evolution of semiconductor technology, spatial light modulators (SLMs) come to be useful for various imaging fields. By using SLM techniques for OSH, the practicality of OSH is improved. These SLM-based OSH methods are termed computational OSH (COSH). In this review, the configurations, recording and reconstruction methods, and proposed applications of COSH are reviewed.MDPI AG, Apr. 2024, Photonics, 11(4) (4), 347 - 347Scientific journal
- In this paper, we have proposed a method of three-dimensional (3D) fluorescence imaging through a scattering medium. The proposed method combines the numerical digital phase conjugation propagation after measurement of the complex amplitude distribution of scattered light waves by the transport of intensity equation (TIE) with followed iterative phase retrieval to achieve 3D fluorescence imaging through a scattering medium. In the experiment, we present the quantitative evaluation of the depth position of fluorescent beads. In addition, for time-lapse measurement, cell division of tobacco-cultured cells was observed. Numerical results presented the effective range of the phase amount in the scattering medium. From these results, the proposed method is capable of recovering images degraded by a thin scattering phase object beyond a small phase change approximation.Optica Publishing Group, Mar. 2024, Optics Express, 32(6) (6), 10599 - 10599[Refereed]Scientific journal

- Quantitative phase imaging by digital holographic microscopy (DHM) is a nondestructive and label-free technique that has been playing an indispensable role in the fields of science, technology, and biomedical imaging. The technique is competent in imaging and analyzing label-free living cells and investigating reflective surfaces. Herein, we introduce a new configuration of a wide field-of-view single-shot common-path off-axis reflective DHM for the quantitative phase imaging of biological cells that leverages several advantages, including being less-vibration sensitive to external perturbations due to its common-path configuration, also being compact in size, simple in optical design, highly stable, and cost-effective. A detailed description of the proposed DHM system, including its optical design, working principle, and capability for phase imaging, is presented. The applications of the proposed system are demonstrated through quantitative phase imaging results obtained from the reflective surface (USAF resolution test target) as well as transparent samples (living plant cells). The proposed system could find its applications in the investigation of several biological specimens and the optical metrology of micro-surfaces.MDPI AG, Jan. 2024, Sensors, 24(3) (3), 720 - 720, English[Refereed]Scientific journal

- Digital holography is a versatile three-dimensional imaging technique that has the ability to record the complex wave-front of an imaged object in two-dimensions and retrieve it in three-dimensions. Several technical challenges of digital holographic systems have been overcome by proposing single-shot acquisition and common-path configurations. However, the limited fiel-of-view (FOV) of digital holography is the most fundamental and technically challenging aspect of this technology. With this in mind, we have developed a digital holographic microscope (DHM) with a doubled FOV together with it leverages single-shot acquisition, common-path, and off-axis configuration and operates in the reflection mode. The double FOV is achieved by spatial frequency multiplexing of two different areas of the object beam by the use of a cube beam splitter. The common-path and off-axis configuration are obtained by employing a plate beam splitter just before the microscope objective. Several experiments are carried out, and the results are presented to demonstrate the validity and effectiveness of the proposed DHM for quantitative phase imaging of (semi) transparent and reflective objects. Based on the experimental results, the proposed microscope shows advanced performance in biomedical imaging as well as inspection of engineered surfaces with its simplicity, higher stability (temporal and mechanical), compactness, low cost, and most importantly double FOV capabilities.AIP Publishing, Nov. 2023, Applied Physics Letters, 123(22) (22), 223702[Refereed]Scientific journal
- Abstract Computational optical scanning holography (COSH) is one of the single-pixel incoherent digital holographic techniques; therefore, three-dimensional fluorescent objects can be measured as a digital hologram with a single-pixel detector. However, due to the requirement of a phase-shifting method to remove unnecessary components from holograms, the number of measurements of COSH is larger than the number of pixels. To reduce the number of measurements, the spatially divided phase-shifting method has been proposed. Similar to the parallel four-step phase-shifting digital holography, the spatially divided phase-shifting method can obtain four phase-shifted holograms simultaneously. However, the spatially divided phase-shifting method has a problem in that the spatial resolution is lower than the original COSH. In this paper, a spatially divided two-step phase-shifting method is proposed to improve spatial resolution. The numerical evaluation results indicate the feasibility of the proposed method. In addition, the proposed method is applied to microscopy for proof of principle experiment. The experimental results indicate the proposed method improves the image quality compared with the conventional spatially divided four-step phase shifting method.IOP Publishing, Oct. 2023, Journal of Optics, 25(12) (12), 124001 - 124001[Refereed]Scientific journal
- Optical scanning holography (OSH) can be applied to 3D fluorescent imaging. However, the optical setup for OSH is complicated due to the requirement of a phase shifter, a 2D mechanical scanner, and an interferometer. Although motionless optical scanning holography (MOSH) can overcome the problem, quantitative phase imaging (QPI) has not yet been realized because MOSH can only obtain incoherent holograms. If QPI in MOSH is realized, MOSH can be applied to various applications. In this Letter, MOSH-based QPI (MOSH-QPI) is proposed. In addition, a simple description of a coherent mode of OSH is presented. In the proof-of-principle experiment, the spatially divided phase-shifting technique is applied to reduce the number of measurements. The feasibility of MOSH-QPI is confirmed by measuring a phase distribution of a microlens array. MOSH-QPI is also applied to measure practical samples, and its results are compared with the experimental results of the conventional one using a Mach–Zehnder interferometer.Optica Publishing Group, Oct. 2023, Optics Letters, 48(20) (20), 5273 - 5273[Refereed]Scientific journal

- In the last few decades, there have been several advances in ultrafast imaging of light propagation with light-in-flight recording by holography (LIF holography), which can capture light propagation as a motion picture with a single shot in principle. Here, we review the recent advances in LIF holography by considering the perspectives of various development of functional imaging techniques and evaluation of LIF holography with numerical simulation methods. The methods for recording multiple motion pictures such as a space-division multiplexing, a pixel-by-pixel-based space-division multiplexing, and an angular multiplexing technique are added extend the capability of LIF holography. The numerical simulation models used for investigating the image characteristics of LIF hologram are discussed. Finally, a summary and conclusion of recent advances in LIF holography is presented.American Association for the Advancement of Science (AAAS), Sep. 2023, Ultrafast Science, 3, 0043[Refereed]Scientific journal

- Defect detection requires highly sensitive and robust inspection methods. This study shows that non-overlapping illumination patterns can improve the noise robustness of deep learning ghost imaging (DLGI) without modifying the convolutional neural network (CNN). Ghost imaging (GI) can be accelerated by combining GI and deep learning. However, the robustness of DLGI decreases in exchange for higher speed. Using non-overlapping patterns can decrease the noise effects in the input data to the CNN. This study evaluates the DLGI robustness by using non-overlapping patterns generated based on binary notation. The results show that non-overlapping patterns improve the position accuracy by up to 51%, enabling the detection of defect positions with higher accuracy in noisy environments.Optica Publishing Group, Nov. 2022, Applied Optics, 61(34) (34), 10126 - 10126Scientific journal

- Recent advances in optical bioimaging and optogenetics have enabled the visualization and manipulation of biological phenomena, including cellular activities, in living animals. In the field of neuroscience, detailed neural activity related to brain functions, such as learning and memory, has now been revealed, and it has become feasible to artificially manipulate this activity to express brain functions. However, the conventional evaluation of neural activity by two-photon Ca2+ imaging has the problem of low temporal resolution. In addition, manipulation of neural activity by conventional optogenetics through the optic fiber can only simultaneously regulate the activity of neurons with the same genetic background, making it difficult to control the activity of individual neurons. To solve this issue, we recently developed a microscope with a high spatiotemporal resolution for biological applications by combining optogenetics with digital holographic technology that can modify femtosecond infrared laser beams. Here, we describe protocols for the visualization, evaluation, and manipulation of neural activity, including the preparation of samples and operation of a two-photon holographic microscope (Figure 1). These protocols provide accurate spatiotemporal information on neural activity, which may be useful for elucidating the pathogenesis of neuropsychiatric disorders that lead to abnormalities in neural activity.Sep. 2022, Journal of visualized experiments : JoVE, (187) (187), English, International magazineScientific journal
- This paper proposed a holographic optical element as a see-through screen for the computer-generated hologram projection system with 3D images. The proposed holographic screen consisted of a linear grating and a lens phase. The linear grating is used to redirect the information light and guide information into the observer's eye and achieve the see-through function. The lens phase is used to magnify the field of view of the holographic projection system. The aberration caused by the screen was analyzed in this paper and the aberration can be pre-corrected in the hologram calculation algorithm. Finally, the proposed system achieved 20.3 by 14.3 degrees field of view at 532 nm laser based on the spatial light modulator with 6.4 µm pixels.Optica Publishing Group, Aug. 2022, Optics Express, 30(19) (19), 33792 - 33792Scientific journal
- We explore the contribution of convolutional neural networks to correcting for the effect of the point spread function (PSF) of the optics when applying ghost imaging (GI) combined with deep learning to identify defect positions in materials. GI can be accelerated by combining GI and deep learning. However, no method has been established for determining the relevant model parameters. A simple model with different kernel sizes was built. Its accuracy was evaluated for data containing the effects of different PSFs. Numerical analysis and empirical experiments demonstrate that the accuracy of defect identification improved by matching the kernel size with the PSF of the optics.Optica Publishing Group, Aug. 2022, Applied Optics, 61(23) (23), 6714 - 6714Scientific journal

- This paper proposes a binocular holographic floating display. The device consists of two phase-modulation spatial light modulators (SLM) and a dihedral corner reflector array (DCRA) element. The conjugate images of the SLMs generated by the DCRA become the system’s exit pupils. Exit pupils that are larger than the pupils of human eyes are arranged to locate at the position of observer's eyes. Therefore, the dimension of the SLM will not limit the viewing angle, although the pixel pitch of the SLM still limits the maximum field of view. For the laser light source, the resolution of the images can achieve 3 arc minutes when the distance between images and DCRA is less than 20 cm. The full-color display function is also performed in the proposed device.Optica Publishing Group, Nov. 2021, Optics Express, 29(23) (23), 38615 - 38615Scientific journal
- Holographic structured illumination combined with optogenetics enables patterned stimulation of neurons and glial cells in an intact living brain. Moreover, in vivo functional imaging of cellular activity with recent advanced microscope technologies allows for visualization of the cellular responses during learning, emotion and cognition. Integrating these techniques can be used to verify the link between cell function and behavior output. However, there are technical limitations to stimulate multiple cells with high spatial and temporal resolution with available techniques of optogenetic stimulation. Here, we summarized a two-photon microscope combined with holographic system to stimulate multiple cells with high spatial and temporal resolution for living mice and their biological application.Nov. 2021, Neuroscience research, 179, 57 - 64, English, International magazine[Refereed]Scientific journal

- Sustained neuropathic pain from injury or inflammation remains a major burden for society. Rodent pain models have informed some cellular mechanisms increasing neuronal excitability within the spinal cord and primary somatosensory cortex (S1), but how activity patterns within these circuits change during pain remains unclear. We have applied multiphoton in vivo imaging and holographic stimulation to examine single S1 neuron activity patterns and connectivity during sustained pain. Following pain induction, there is an increase in synchronized neuronal activity and connectivity within S1, indicating the formation of pain circuits. Artificially increasing neuronal activity and synchrony using DREADDs reduced pain thresholds. The expression of N-type voltage-dependent Ca2+ channel subunits in S1 was increased after pain induction, and locally blocking these channels reduced both the synchrony and allodynia associated with inflammatory pain. Targeting these S1 pain circuits, via inhibiting N-type Ca2+ channels or other approaches, may provide ways to reduce inflammatory pain.American Association for the Advancement of Science (AAAS), Mar. 2021, Science Advances, 7(12) (12), eabd8261 - eabd8261[Refereed]Scientific journal

Abstract We present a multimodal imaging system based on simple off-axis digital holography, for simultaneous recording and retrieval of cross-sectional fluorescence and quantitative phase imaging of the biological specimen. Synergism in the imaging capabilities can be achieved by incorporating two off-axis digital holographic microscopes integrated to record different information at the same time. The cross-sectional fluorescence imaging is realized by a common-path configuration of the single-shot off-axis incoherent digital holographic system. The quantitative phase imaging, on the other hand, is achieved by another off-axis coherent digital holographic microscopy operating in transmission mode. The fundamental characteristics of the proposed multimodal system are confirmed by performing various experiments on fluorescent beads and fluorescent protein-labeled living cells of the mossPhyscomitrella patens lying at different axial depth positions. Furthermore, the cross-sectional live fluorescence and phase imaging of the fluorescent beads are demonstrated by the proposed multimodal system. The experimental results presented here corroborate the feasibility of the proposed system and indicate its potential in the applications to analyze the functional and structural behavior of biological cells and tissues.[Refereed]Scientific journal - Nov. 2020, JOURNAL OF OPTICS, 22(11) (11), English[Refereed]Scientific journal

- Computational ghost imaging (CGI) is one of several attractive techniques for optical measurement because it can determine two-dimensional structures of target objects without using an image sensor. However, conventional CGI is not suitable for practical use in terms of measurement time. In this paper, we report on reducing the optical measurement time in CGI and propose a new CGI implementation. The proposed method utilizes the wide bandwidth of laser diodes. We can obtain a set of speckle patterns required in computational ghost imaging in a significantly shorter time by changing emission patterns. Consequently, this method is suitable for high-speed measurements. The concept of the method is described and verified by numerical analysis. Further, optical setup for the experimental verification is assembled. As verified with experiments and signal processing, the proposed method can provide reconstructed images of targets.MDPI AG, Nov. 2019, Applied Sciences, 9(22) (22), 4807 - 4807[Refereed]Scientific journal

- A new type of functional optical microscope system called three-dimensional (3D) stimulation and imaging-based functional optical microscopy (SIFOM) is proposed, to the best of our knowledge. SIFOM can precisely stimulate user-defined targeted biological cells and can simultaneously record the volumetric fluorescence distribution in a single acquisition. Precise and simultaneous stimulation of fluorescent-labeled biological cells is achieved by multiple 3D spots generated by digital holograms displayed on a phase-mode spatial light modulator. Single-shot 3D acquisition of the fluorescence distribution is accomplished by common-path off-axis incoherent digital holographic microscopy in which a diffraction grating with a focusing lens is displayed on another phase-mode spatial light modulator. The effectiveness of the proposed functional microscope system was verified in experiments using fluorescent microbeads and human lung cancer cells located at various defocused positions. The system can be used for manipulating the states of cells in optogenetics.Nov. 2018, Optics letters, 43(21) (21), 5447 - 5450, English, International magazine[Refereed]Scientific journal

- We have developed a detection method of the state of water using near-infrared light-absorption. In this paper, a new evaluation index of the frozen state of water is proposed. In this case, we focused on the light-absorption characteristics of water. The experimental results showed that the absorption peak shifts to longer wavelength when the water state changes into ice state. To remove the affect of the scattering by bubbles generated in the freezing process and the thickness of the water layer, we have proposed a new evaluation index based on absorbed light intensity ratio at two wavelengths. The index is constant even when the layer thickness changes from 1mm to 3mm and is not also affected by light scattering. This result indicates that the proposed evaluation index can be used as a criterion to detect the liquid phase (water state) or the solid phase (ice state). It has been confirmed that the method using the index is effective for monitoring the water freezing process with supercooling by the experiment.The Society of Instrument and Control Engineers, Oct. 2016, Transactions of the Society of Instrument and Control Engineers, 52(10) (10), 531 - 537, Japanese[Refereed]Scientific journal

- We propose a color digital holography by using spectral estimation technique to improve the color reproduction of objects. In conventional color digital holography, there is insufficient spectral information in holograms, and the color of the reconstructed images depend on only reflectances at three discrete wavelengths used in the recording of holograms. Therefore the color-composite image of the three reconstructed images is not accurate in color reproduction. However, in our proposed method, the spectral estimation technique was applied, which has been reported in multispectral imaging. According to the spectral estimation technique, the continuous spectrum of object can be estimated and the color reproduction is improved. The effectiveness of the proposed method was confirmed by a numerical simulation and an experiment, and, in the results, the average color differences are decreased from 35.81 to 7.88 and from 43.60 to 25.28, respectively.Dec. 2011, Applied optics, 50(34) (34), H177-82, English, International magazineScientific journal

- We report three-dimensional (3D) motion-picture imaging of a biological object in the microscopic field of view by parallel phase-shifting digital holographic microscopy using a high-speed camera. Parallel phase-shifting digital holographic microscopy is a technique for high-quality and instantaneous 3D imaging of specimens in the microscopic field of view. This microscopy has been experimentally verified. This time, by applying a high-speed camera to the constructed optical system, we succeeded in recording motion-pictures of a dynamic motion of a biological object in water at 20,000 frames-per-second, which is the fastest among the previous reports on 3D imaging of a biological object.The Institute of Image Information and Television Engineers, 2011, ITE Technical Report, 35, 33 - 36, Japanese[Refereed]

- For practical use of image reconstruction in a steady-state diffusion optical tomography, a weight function is analytically derived in a linear perturbation approach. We show that the weight function at any voxel in the medium is given by a product of a sensitivity function at the voxel and a mean optical pathlength in the voxel, whose two parameters have independent behavior to each other. By use of Monte Carlo simulation, it is found that the mean path length is easily obtained without stochastic calculation by scattering coefficient in the medium. Weight function derived by the proposed method is in good agreement with exact solution based on Monte Carlo method.The Institute of Electrical Engineers of Japan, Jul. 2007, IEEJ Transactions on Fundamentals and Materials, 127(7) (7), 397 - 401, English[Refereed]

- Space-bandwidth extension methods in parallel phase-shifting digital holography using a commercially available polarization-imaging cameraWe present methods for extending the space bandwidth available for recording an object wave in the case where a commercially available polarization-imaging camera is used for recording a hologram required for parallel phase-shifting digital holography. Parallel phase-shifting digital holography has been proposed for achieving single-shot wide-bandwidth three-dimensional imaging and can be implemented by using the polarimetric camera having four polarization-detection channels. However, when such the camera is used, most of the space bandwidth is discarded and then both the field of view and resolution are decreased. In this presentation, an optical implementation and image-reconstruction algorithm for extending the bandwidth are proposed and then these methods and previously proposed techniques are comparatively evaluated.The Institute of Image Information and Television Engineers, Sep. 2013, ITE Technical Report, 37(37) (37), 29 - 32, Japanese

- Study on 3D Display Based on Wavefront Reconstruction for Wide Viewing AngleHolographic display is considered to be identical for three dimensional display.Electronic holography is attractive for the display. In the present device technology, however, viewing angle of that is not enough to practical use.

- Multi-parameter imaging system based on single-shot phase-shifting digital holographySingle-shot phase-shifting digital holography is a technique capable of recording three-dimensional (3D) and quantitative phase distributions simultaneously with a single-shot exposure. We have proposed a holographic technique for capturing the information of a 3D structure, phase, temporal change, polarization, and wavelength dependency, which is based on single-shot phase-shifting technique. In this report, we present the basic concept and an optical system for recording motion pictures of wavelength dependency of an object. In the presented system, a monochromatic image sensor captures both a wide-area 3D structure and optical properties of multi-wavelengths with a single-shot exposure. We constructed the optical system and experimented to verify the effectiveness of the presented system. Then, space-bandwidth product for recording the object wave in each wavelength is compared with a conventional off-axis configuration utilizing angular multiplexing technique.The Institute of Image Information and Television Engineers, 23 Oct. 2012, ITE Technical Report, 36(43) (43), 35 - 38, Japanese
- Single-shot dual-illumination phase unwrapping using a single wavelength and its application to digital holographyWe present a single-shot dual-illumination phase-unwrapping technique using a single wavelength. Although dual-illumination phase unwrapping is a technique capable of high-accuracy three-dimensional (3D) shape measurement for even though a stepped-object, single-shot imaging was impossible because of the requirement of sequential recording of multiple holograms. In the presented technique, an object is illuminated by two laser beams simultaneously. The beams are emitted from the same laser, whose illumination angles and polarizations are different. Then two types of the object waves generated by the two beams are separately and simultaneously recorded by a polarization-imaging camera. We simulated and experimented the presented technique, and a 3D shape of an object was reconstructed without wrapping.The Institute of Image Information and Television Engineers, 31 Aug. 2012, ITE Technical Report, 36(36) (36), 1 - 4, Japanese

- Comparison of Recording Characteristics of Multiresolution Coding in Holographic MemoryIn a reflection-type holographic memory with a speckle shift-multiplexing, we investigate the recording characteristics of multiresolution coding, which represents different data pages observed by different resolution, for increasing the storage capacity. Numerical results indicate that 3:16 block coding shows superior characteristics in signal-to-noise ratio and bit error rate to 2:4 coding when a data page with 2 levels resolution is used.The Institute of Electronics, Information and Communication Engineers, 09 Sep. 2011, IEICE technical report, 111(206) (206), 33 - 36, Japanese

The characteristics of the angle-resolved probe (ARP) were also completely explained by assuming a virtual dipole probe for its spatial sensitivity distribution (SSD). Furthermore, it was shown that the SSD of the ARP can be synthesized by using the analytical solution of the light diffusion equation, and as a result of applying it to the time-resolved measurement, we obtained the prospect that the simulation time would be significantly reduced.

First, a digital holography system based on the technique was designed and constructed for a reflective object. The recording and reconstruction capability of 3D images of both the front and back sides of the reflective object was experimentally confirmed by the system. Next, another digital holography system based on the technique was designed and constructed for a transparent object. This system is based on parallel phase-shifting digital holography using a high-speed polarization imaging camera. To record and reconstruct the 3D image of the internal 3D distribution of refractive index of a transparent object, Abel inversion was employed. Omni-directional 3D imaging of transparent and dynamic gas flow was experimentally demonstrated by the system.

We fabricated a multimodal DHM that can obtain simultaneously two-dimensional fluorescence distribution and 3D phase distribution. The effectiveness of the proposed DHM was confirmed by the experimental results of plant cells and mouse's brain cells.

In the previous work, we investigated the imaging characteristics of the transmitted-type HIE. In this work, we investigate the HIE with high diffractive efficiency on different wavelength range from the HIE for low vision people in order to obtain images for the measurement of the distance to the forward obstacle. Experimental results show that the imaging system with the HIE for the measurement of the distance measurement can obtain images the targets as a forward obstacle independently.

In the developed quantum object recognition algorithm, quantum entanglement and quantum superposition are used to process the data with very high speed. To apply the developed algorithm to a large number of objects, a method of automatic feature extraction using SURF (Speeded Up Robust Features) and k-means is developed. As a large number of objects, 1,001 images such as alphabet are used. Four featured images to each original image are extracted. As a result, average probability amplitude of the detection of the correct image is 0.92. We confirmed that the developed algorithm has high recognition capability to a large number of objects.Competitive research funding

(1) Improvement of spectral bandwidth : Femto-second pulse shaping is one of the interesting applications of photorefractive devices. However, the spectral bandwidth of conventional AlGaAs multiple quantum well devices are limited within 4 nm in wavelengths. This bandwidth is too narrow to handle femto-second pulses. In order to broaden the spectral region, we have employed an asymmetric coupled quantum well structure, where two different quantum wells are coupled through thin coupling layers. We can tailor the electro-absorption spectrum of excitonic resonance by controlling the thickness and depth of wells and coupling layers. We have designed and fabricated several asymmetric quantum well structures and have measured the photorefractive properties. Finally, the spectral bandwidth of response is broadened up to 12 nm in wavelength. Moreover, the asymmetric quantum well structure improved the sensitivity substantially. (2) Improvement of spatial resolution : In p-i-n diode structures, the external field is applied longitudinally through the multiple quantum well layers. In this geometry, photo-induced charges are trapped in cladding layers. Therefore, the energy step between the multiple quantum well layers and the cladding layers plays an important roll in the performance of this device. We have fabricated several device structures that have different potential energy of cladding layers by changing the fractions of Al and Ga. We found that the reduction of energy step improves the spatial resolution of device. It is found that the temporal behavior is also influenced by the potential of cladding layer. (3) New material GaN : We demonstrated, at the first time, the photorefractive effect in a semi-insulating GaN thin layer at the wavelength of 363.6 nm, which is the shortest wavelength at which the photorefractive effect has ever been demonstrated in semiconductors.

They have lots of potential applications, such as, high-speed parallel signal processing devices for next generation information network systems, high-speed adaptive sensor for vibration detection, near-infrared optical devices for biomedical applications, etc. The target of this research was to develop high-speed and high-sensitivity photorefractive materials using InGaAs/GaAs semiconductor multiple quantum wells. (1) We measured the lifetime and diffusion coefficient of photocarriers using time-resolved four wave mixing. The carrier lifetime is about 100 ps in proton-implanted samples. (2) We fabricated the photorefractive devices in quantum confined Stark geometry. The devices consist of the MQW layers sandwiched by SiO2 insulating layers. The diffraction efficiency is improved by 20 times in comparison with the Franz-Keldysh devices. However, the spatial resolution became poor. (3) In order to improve the spatial resolution, we used the low-temperature grown GaAs layers for insulating layers instead of SiO2 layers. This new structure substantially improved the spatial resolution of the devices. (4) We fabricated the devices that work at 1064 nm, that is, the wavelength of Nd : YAG laser. To fit the exciton resonance to this wavelength, the fraction of indium is increased in InGaAs quantum well layers. However, this results in large lattice constant mismatch between InGaAs and GaAs layers. The MQW layers are successfully grown on the properly designed buffer layer which releases the strain in the MQW layers.

At first proposal, we tried the method using photo-sensitive polymers. Unfortunately, an British research group has reported the same results, thus, we changed the research direction slightly. We chose photorefractive materials instead of photo-sensitive polymers as a recording materials of the three dimensional interference pattern. Because the change of the refractive index is up to the order of 10^<-2>, photonic band gap cannot be realized. However, this kind of three dimensional modulation of the refractive index causes several remarkable effects, such as anomalous group velocity, and a promising candidate for the future photonic devices. When we consider the three dimensional four-wave interference, we have to take into account of the relation of the polarization of hour waves as well as the direction of k vectors. We investigated the effect of the polarization on the three dimensional interference theoretically. Also we compared the simultaneous exposure with all four waves and the sequential exposure with each set of two waves. We also studied the non-volatile recording of the three dimensional index patterns in photorefractive crystals. We tried two methods. One is a method using three levels of one element, and the other is that using two different elements as impurities. We studied two photon recording in photorefractive materials with these two methods both theoretically and experimentally. We obtained fundamental knowledge about the non-volatile recording.

(1) We have fabricated InGaAs/GaAs multiple quantum well photorefractive devices that have the sensitivity at the wavelength of around 1mum. After the epitaxial growth of quantum well layrs, the deep level defects are introduced by proton implantation. We can make the samples semi-insulating up to 10^5OMEGAcm by this process. Than we measured the amplitudes of refractive-index and absorption gratings by the two- wave mixing. The coupling gain of about 40cm^<-1> are measured at the wavelength of 930-940nm. (2) In order to improve the beam quality of high-power broad area laser diode, we carried out the injection locking of laser diodes through a double phase conjugator using photorefractive BaTiO_3, which make the beam coupling efficient and adjustment-free. We finally achieved the longitudinal single mode operation of high-power laser diode up to 500mW.The degree of spatial coherence is better than 80%. (3) In order to realize the high-density interconnection, we have investigated 3 dimensional waveguides in photorefractive LiNbO_3, which made of the array of high refractive index dots. I have proved that dot-array successfully guides the wave with low loss. One of the advantage of the dot-array is easy to change the structure of the waveguides.
