摘要 ：
Single-molecule localization microscopy (SMLM) has been applied as a powerful tool in the visualization of biological samples. The obtained details about the fine structures inside the cells or tissues, on the spatial scale of much smaller than the size that defined by the diffraction limit of the optical system, are important for the understanding of the dynamics and organization of the living process. In this paper, by exploring the direct correlation of real-valued holograms in fluorescence self-interference digital holography (SIDH), an imaging method is proposed for 3D localization and dynamic 3D tracking of nanoparticles. The trend of 3D localization accuracy under different axial positions is studied in detail. An appropriate mathematical model is used to fit the cross-correlation curve of the hologram to determine the axis coordinate of the point source. The validity of the proposed method is demonstrated in simulation and experiments. This method does not require phase shift technology. The 3D coordinates of particles can be obtained through a single real-valued hologram using the proposed algorithm. Therefore, we believe the developed method has unique advantages in the 3D visualization of dynamic events that happened on the biomolecules inside the cellular structures.

摘要 ：
Ghost imaging (GI) is an imaging method that reconstructs object information via light-intensity correlation measurements. The unconventional imaging mechanism of GI makes it suitable for imaging in scattering medium, for instance, turbid liquid, biological tissues, etc. However, the strong background noise in the reconstructed images is still the bottleneck problems. In this paper, we focus on the improvements of the reconstructions in underwater GI and propose a speckle decomposition and fusion method for suppressing the noise. The approach utilized computational ghost imaging framework and dictionary learning to acquire highand low-frequency components that are better suited for image feature-based reconstruction. Furthermore, once the suitable threshold has been established, the speckles captured from the reference path are decomposed using the Nonsubsampled Contourlet Transform (NSCT). The acquired high- and low-frequency are then correlated with the overall optical intensity that captured by the bucket detectors. Ultimately, a multi-scale inverse NSCT transformation is employed to produce the final fusion-reconstructed image. The quantitative evaluation of the reconstructed image quality was conducted. In contrast to previous methodologies, the proposed method offers significant enhancements of the underwater GI imaging quality.

Optical computing technology is a unique computing system based on optical devices and computing functions, which significantly differs from the traditional electronic computing technology. On the other hand, optical computing technology offers the advantages such as fast speed, low energy consumption, and high parallelism.

摘要 ：
Conventional optical telescope only collect the amplitude of optical wavefront with incoherent light, while selfinterference incoherent digital holography offers a unique method of coding both the optical wavefront amplitude and phase information by interference patterns. We developed an adaptive non-scanning threedimensional (3D) telescopic imaging technique based on self-interference incoherent holography with a geometric phase lens (GP-SIDH). The phase recorded in the point spread hologram and the incoherent selfinterference extended holograms are employed to detect spatial positions, correct optical aberration and extract edges by computational reconstruction. The 3D imaging and position detection performances of our proposed method are investigated. Both simulations and experimental results show that the proposed method exhibits better performances for different depth objects imaging and space position detection. Furthermore, this system can be easily modularization and implanted into any existing optical telescopic system owing to its simplicity and convenience. The proposed approach can be a powerful tool for the multi-objects long-workingdistance imaging, which is more valuable for telescope application.

摘要 ：
Edge enhancement with incoherent illumination is an important research branch of optical imaging and information processing, which presents valuable potential application in target recognition, biomedical microscopy, optical defects detection, optical localization and so on. However, the incoherent optical imaging and information processing system is linear invariable of light intensity transfer and there is not an accurate correspondence spatial frequency plane of object complex-amplitude, thus it is limited to obtain edge enhancement imaging by spatial filter in incoherent system. We proposed a computational incoherent edge enhancement imaging based on self-interference digital holography (SIDH). SIDH offers the incoherent object complex-value holograms which is consisted of the incoherent superimposing point spread holograms. The phase of the point spread holograms not only code the depth information of corresponding object-point, but also the difference of the two interference beams and the aberration introduced by recording scheme. The characteristics of incoherent self-interference hologram are employed to utilize edge enhancements and adaptive aberration correction during reconstruction, thus the Laguerre-Gaussian vortex angle spectrum algorithm of SIDH hologram are modified and developed, simultaneous regulating both amplitude and phase in the reconstruction process. Both experimental results demonstrate our method exhibits better performances for edge extraction, background noise can be well suppressed, edge becomes sharper and high contrast. The proposal has also been verified that it can be used for direction-optional edge enhancement, edge enhancement with adaptive aberration correction and edge enhancement imaging of different depth objects simultaneously.

摘要 ：
Fluorescence microscopy is crucial in various fields such as biology, medicine, and life sciences. Fluorescence self- interference holographic microscopy has great potential in bio-imaging owing to its unique wavefront coding characteristics; thus, it can be employed as three-dimensional (3D) scanning-free super-resolution microscopy. However, the available approaches are limited to low optical efficiency, complex optical setups, and single imaging functions. The geometric phase lens can efficiently manipulate the optical field's amplitude, phase, and polarization. Inspired by geometric phase and self-interference holography, a self-interference fluorescent holographic microscope-based geometric phase lens is proposed. This system allows for wide-field, 3D fluorescence holographic imaging, and edge-enhancement from the reconstruction of only one complex-valued hologram. Experiments demonstrate the effectiveness of our method in imaging biological samples, with improved resolution and signal-to-noise ratio. Furthermore, its simplicity and convenience make it easily compatible with existing optical microscope setups, making it a powerful tool for observing biological samples and detecting industrial defects.

摘要 ：
Underwater imaging technologies play a critical role in military operations, marine research and development, as well as engineering applications. However, the underwater environment with various of extraneous matter usually presents strong back-scattering and photon absorption effects when light propagates in this kind of media, thus leading to the poor imaging quality. Polarization difference imaging is an available method of suppressing back-scattered light while the method often results in lower brightness and some frequency components loss. A parameter optimization-based polarization difference fusion imaging method for underwater turbid medium is proposed in this paper. Back-scattering and polarization intensity can be estimated accurately by utilizing our proposed method, and further incorporates the estimated parameter values to better represent the global features and information of the scene. Experimental imaging tests were conducted on different targets, and the results demonstrate that the proposed method effectively overcomes the non-uniform illumination problem in underwater turbid medium conditions, enabling high-quality imaging of targets in such environments.

摘要 ：
Interferenceless coded aperture correlation holography (I-COACH) is a rapidly developing indirect three-dimensional (3D) imaging technique. However the ideal point spread function of imaging system is not obtained in most cases, the object hologram is usually correlated with the system response of a limited-size pinhole during the reconstruction process. As a result, the quality of reconstructed images is contaminated by noise. In this paper, the system response of a limited-size pinhole is regarded as the convolution of the pinhole (as an object) intensity and the ideal point spread function of I-COACH, a mathematical analysis of the background noise is conducted and a general high-quality reconstruction mathematic model of I-COACH system is derived when a limited-size pinhole is used to record point spread hologram, in which the reconstructions and noise is separated. Then a non-iterative cross-correlation reconstruction algorithm has been developed here to achieve high-quality 3D reconstruction. The proposed method has been implemented on a regular I-COACH system in both transmission as well as reflection illumination modes to demonstrate the imaging ability of our method. The experimental results show that high quality reconstructions can be achieved by our proposal with a single-exposure object hologram.

摘要 ：
Incoherent optical cryptosystem is promising for its immunity against coherent noise and insensitivity to misalignment, and compressive encryption is desirable considering the increasingly demand on the exchange of encrypted data via Internet. In this paper, we propose a novel optical compressive encryption approach with spatially incoherent illumination based on deep learning (DL) and space multiplexing. For encryption, the plaintexts are individually sent to the scattering-imaging-based encryption (SIBE) scheme where they are transformed to scattering images with noise appearances. Afterwards, these images are randomly sampled and then integrated into a single package (i.e., ciphertext) by space multiplexing. The decryption is basically the inverse of the encryption, while it involves an ill-posed problem (i.e., recovering the noise-like scattering image from its randomly sampled version). We demonstrated that such a problem can be well resolved by DL. The proposal is radically free from the cross-talk noise existing in many current multiple-image encryption schemes. Also, it gets rid of the linearity bothering the SIBE and is hence robust against the ciphertext-only attack based on phase retrieval algorithm. We present a series of experimental results to confirm the effectiveness and feasibility of the proposal.

摘要 ：
Motivated by the key role of point spread function in an imaging system, we propose an interferenceless coded aperture correlation holographic (I-COACH) technology with low speckle and high energy efficiency annular sparse coded phase mask (CPM) as system pupil to improve imaging performance. In the proposed method, a modified Gerchberg-Saxton (GS) algorithm is proposed to obtain a low speckle and high energy efficiency annular sparse CPM and to suppress speckle and increase the intensity of the holograms. Therefore, the randomly distributed amplitude in the bandwidth of the GS algorithm is replaced by the annular amplitude to determine the spatial position, and the band-limited random phase and quadratic phase are used as the initial phase to approximately meet band-limited conditions; meanwhile, in the iterative process of the algorithm, appropriate constraints are imposed on the information within and outside the band limit. All are used for obtaining the CPM with low speckle and high energy efficiency. Therefore, the proposed technique here is coined as low speckle I-COACH owing to the characteristics of CPM and imaging performances. The experimental results show that, under the same experi mental conditions, the proposed method can obtain holograms with low speckle and intensity enhancement of about 8%, and further improve the quality of reconstructed images due to the improvement signal-to-noise ratio (SNR) of the holograms. The proposed method provides a powerful reference method for further expanding the I-COACH system to the field oflow-intensity optical signals detection and imaging. (C) 2022 Optica Publishing Group
