The theory of the optical properties of an absorbing periodically stratified medium is applied to the spectral and angular dependence of the reflectivity of mollusk shells, which are almost-periodic structures of aragonite plates alternating with thinner organic layers. The reflectivity of s and p polarizations show strong variation as the angle of incidence passes through the stop bands of the corresponding ideal non-absorbing periodic structure. For both polarizations of incident light, and at most angles of incidence, the blue and green wavelengths are reflected more than the red-hence the blue-green appearance of mollusk shells.

Stereo vision technology based on line structured light can effectively solve the problem of a three-dimensional (3D) reconstruction of a smooth surface. A method for 3D reconstruction of mobile binocular stereo vision based on push-broom line structured light for a workpiece surface is presented in this paper. The subpixel coordinates of the light strip centers of the line structured light are obtained by the Steger algorithm while the binocular module moves along the guide rail, and the polar constraint is used to achieve the matching of the extracted light strip centers. As a result, the 3D coordinates of the light strip centers in each location can be calculated because of the known interior and external parameters of the binocular module. To obtain the 3D point cloud data of the entire surface, a relative pose optimization method with respect to the initial frame is proposed, which accurately estimates the pose of the cameras in each location with respect to that in the initial location and unifies the 3D coordinates of the light strip centers in each location to the datum coordinates. The relative pose optimization method first estimates the rough values by using the direct linear transform method, and then iteratively calculates the refined solutions based on the principle of minimizing the re-projection errors. Simulation data and substantial experimental results validate the effectiveness of our method. Our method is compared to the direct linear transform method and the frame-by-frame transfer method, and the root mean square error (RMSE) of the distance from 3D point cloud to fitted plane is used to evaluate the 3D reconstruction accuracy. The repeatability experiment shows that the RMSE from our method is as low as 0.83 mm.

To mitigate the influence of the relative positional relationship between circles on camera calibration, this study explores the double contact of dual circles with dual circular points. We demonstrate that one of the generalized eigenvectors of two dual circles corresponds to the line passing through their respective centers. Moreover, we establish a methodology to identify this line from the three generalized eigenvectors and show that, regardless of the positional arrangement of the three co-planar circles, the image of the circular points can be constructed by calculating the image of this line. Consequently, the applicability of circles as calibration templates is expanded, enabling the development of a novel optimization technique for fitting circular images with enhanced calibration precision.

In this paper, we propose a confocal microscopy based on dual blur depth measurement (DBCM). The first blur is defocus blur, and the second blur is artificial convolutional blur. First, the DBCM blurs the defocus image using a known Gaussian kernel and calculates the edge gradient ratio between it and the re-blurred image. Then, the axial measurement of edge positions is based on a calibration measurement curve. Finally, depth information is inferred from the edges using the original image. Experiments show that the DBCM can achieve depth measurement in a single image. In a 10×/0.25 objective, the error measured for a step sample of 4.7397 µm is 0.23 µm. The relative error rate is 4.8%.

In some situations, the beam is partially blocked by an obstacle during propagation, and the influence of the obstacle and ways to decrease the influence have been studied for practical applications. The self-healing effect of Bessel beams is considered as one potential technology for this. The optical pin beam (OPB) can evolve into a Bessel-like beam and can retain its robust property after long-distance propagation. In this paper, we study the propagation property of an OPB after it is partially blocked by an obstacle. We observe the self-healing effects of the OPB and find that it exhibits robust self-healing abilities. An experiment is conducted to confirm the self-healing effect of the OPB. As one example of the application of the self-healing effect, the radiation forces of an obstructed OPB are calculated. Our findings may have important applications in various fields such as micro-imaging, trapping, and long-distance optical communication under disturbance conditions.

Manipulation of polarization states in a complex structured optical field during propagation has become an important topic due to its fundamental interest and potential applications. This work demonstrates the effect of the caustic and twisting phases on the polarization states of a vector beam experimentally and theoretically. The novel properties of polarization evolution, especially the conversions of different states of polarization (SoPs) in a twisted caustic vector beam, occur during propagation in free space because of the modulation of twisting and caustic phases. The orthogonal polarization components tend to appear on the beam centers of two foci, and the two focal distances are closely related to the caustic and twisting phases. The twisting and caustic phases can manipulate the conversions between linear and circular polarization components that occur during propagation. These results provide a new approach to more complex manipulations of a structured optical field, especially in tailoring the evolution of polarization states and two foci. They may find potential applications in the corresponding field.

We show the construction of 3D solids (volumetric 3D models) of SARS-CoV-2 viral particles from the tomographic studies (videos) of SARS-CoV-2-infected tissues. To this aim, we propose a video analysis (tomographic images) by frames (medical images of the virus), which we set as our metadata. We optimize the frames by means of Fourier analysis, which induces a periodicity with simple structure patterns to minimize noise filtering and to obtain an optimal phase of the objects in the image, focusing on the SARS-CoV-2 cells to obtain a medical image under study phase (MIS) (process repeated over all frames). We build a Python algorithm based on Legendre polynomials called “2DLegendre_Fit,” which generates (using multilinear interpolation) intermediate images between neighboring MIS phases. We used this code to generate m images of size M × M , resulting in a matrix with size M × M × M (3D solid). Finally, we show the 3D solid of the SARS-CoV-2 viral particle as part of our results in several videos, subsequently rotated and filtered to identify the glicoprotein spike protein, membrane protein, envelope, and the hemagglutinin esterase. We show the algorithms in our proposal along with the main MATLAB functions such as FourierM and Results as well as the data required for the program execution in order to reproduce our results.
我们展示了从SARS-CoV-2感染组织的断层扫描研究(视频)中构建的SARS-CoV-2病毒颗粒的3D固体(体积3D模型)。为此，我们建议按帧(病毒的医学图像)进行视频分析(断层图像)，并将其设置为元数据。我们通过傅里叶分析优化帧，该分析通过简单的结构模式诱导周期性以最小化噪声滤波并获得图像中物体的最佳相位，重点关注SARS-CoV-2细胞以获得研究阶段(MIS)下的医学图像(在所有帧上重复此过程)。我们构建了一个基于Legendre多项式的Python算法，称为“2DLegendre_Fit”，它在相邻的MIS阶段之间生成(使用多线性插值)中间图像。我们使用此代码生成m张大小为m × m的图像，得到大小为m × m × m的矩阵(3D实体)。最后，我们在几个视频中展示了SARS-CoV-2病毒颗粒的3D固体，作为我们结果的一部分，随后旋转和过滤以识别糖蛋白刺突蛋白，膜蛋白，包膜和血凝素酯酶。我们在我们的提案中展示了算法以及主要的MATLAB函数，如FourierM和Results，以及程序执行所需的数据，以便重现我们的结果。

Optical coherence tomography (OCT) is a noninvasive optical imaging technique that can be used to produce three-dimensional images of fingerprints. However, the low quality and poor resolution of the regions of interest (ROIs) in OCT images make it challenging to segment small tissues accurately. To address this issue, a super-resolution (SR) network called ESRNet has been developed to enhance the quality of OCT images, facilitating their applications in research. Firstly, the performance of the SR images produced by ESRNet is evaluated by comparing it to those generated by five other SR methods. Specifically, the SR performance is evaluated using three upscale factors (2×, 3×, and 4×) to assess the quality of the enhanced images. Based on the results obtained from the three datasets, it is evident that ESRNet outperforms current advanced networks in terms of SR performance. Furthermore, the segmentation accuracy of sweat glands has been significantly improved by the SR images. The number of sweat glands in the top view increased from 102 to 117, further substantiating the performance of the ESRNet network. The spiral structure of sweat glands is clear to human eyes and has been verified by showing similar left-right-handed spiral numbers. Finally, a sweat gland recognition method for the SR 3D images is proposed.

We predict the reversal of the phase chirality before and after the focal plane during propagation based on ray tracing. The interference patterns of a focused vortex beam (FVB) and a plane beam during propagation verify the fact of phase chirality reversal through diffraction theoretical simulations and experiments. Also, we deduce an analytical expression for the caustic based on the ray equation, which effectively represents the change of the hollow light field during propagation. Simulation and experimental results demonstrate the effectiveness of the caustic in describing the variation of the global hollow dark spot radius. Furthermore, based on the caustic results at the focal plane, we customize FVBs with the same dark spot radii but different topological charges. Our research results reveal the characteristics of the light field and phase distribution of the FVB during propagation, which will expand our understanding of the properties of the FVB and provide a reference value for applications such as chiral particle manipulation and topological charge recognition.

To address the digital medium preference of the millennial generation, this study utilizes augmented reality (AR) technology for rendering color paper cuttings by developing a mobile terminal based on Unity 3D and 3ds Max to demonstrate digital works scanned by paper-cutting entities. Three subjective scaling experiments are conducted to evaluate the aesthetics, viewership, and impression of four genres of digital color paper cutting. The results show that observers have more preference for warm background with the maximum scaling value at the 7.5 mm/s playback speed and a specific superimposed order. Importantly, current experimental design and interactive evaluation provide a reference for AR display parameters.
