Bound states in continuum (BIC) have been proposed as a means to efficiently improve the light-matter interaction of metasurface. While breaking the mirror symmetry of structure and developing BIC into a reachable and observable quasi-BIC, it is usually accompanied by the chiral phenomenon with high quality (Q) factor. Here, we report a spin-sensitive photodetector in infrared (NIR) region, which is composed of a silicon metasurface with chiral quasi-BIC, a silver layer, and a thermoelectric layer. A chiral quasi- BIC supported by a silicon metsurface can be realized under normal incidence. Based on Finite element method (FEM) simulation, a silicon metsurface with a silver layer shows a high Q-factor of 958.6 with a giant absorption circular dichroism (CD) of 0.83. Subsequently, we study the thermal performance of the chiral absorbers by using Heat Transfer module of Comsol. Combining with the thermoelectric material bismuth telluride, we calculate the differential photothermoelectric effects of the system under circular-polarized light (CPL) irradiation. When the incident flux is 100 W/cm2, the output voltage under RCP (LCP) light reaches 0.59 mV (0.08 mV), which can be used for polarization detecting. Therefore, our designed structure incorporating thermoelectricity broadens the applications of chiral BIC in sensors and detectors.

This study proposed an optimization method for freeform progressive addition lenses (PALs) based on the coincident degree of weight distributions (WD) for power deviation and astigmatism. Compared with the existing methods which were limited in optimizing weight distributions (WDs) for power deviation and astigmatism, our proposed approach offers a more refined optimization. In the design phase, the power deviation and astigmatism of these lenses were evaluated using the existing surface shape. Compared with the prescriptions of the patients, the coincident degrees between the obtained distributions and prescriptions of the PAL power and astigmatism were calculated in the multi-view axis condition. Normalization processing of coincident degrees was performed, yielding the corresponding threshold value of weight distributions and optimizing the allocated coincident degrees. Based on a minimization error function model, two PALs were designed, simulated, machined, and evaluated using a commercial software. The optimized method reduced peripheral astigmatism and improved the optical properties of PALs. The proposed approach optimizes the freeform PALs and enhances their design optimization in optometry.
本研究提出了一种基于功率偏差和散光重量分布（WD）重合度的自由曲面渐进加法镜片（PALs）优化方法。现有方法在优化功率偏差和散光的重量分布（WDs）方面存在局限性，与之相比，我们提出的方法提供了更精细的优化。在设计阶段，我们利用现有的表面形状对这些镜片的功率偏差和散光进行了评估。与患者的处方相比，在多视轴条件下，计算得到的 PAL 功率和散光分布与处方之间的重合度。对重合度进行归一化处理，得出相应的权重分布阈值，并优化分配的重合度。根据最小化误差函数模型，使用商业软件设计、模拟、加工和评估了两个 PAL。优化方法减少了周边散光，改善了 PAL 的光学性能。所提出的方法优化了自由形态 PAL，提高了其在验光配镜中的设计优化水平。

In the context of addressing a noisy turbulence-degraded image, it is common to use a denoising low-pass filter before implementing a deblurring algorithm. However, this filter not only suppresses noise but also induces a certain degree of blur into the degraded image. This blur effect causes a blurred estimate of the true blur kernel and ultimately leads to a distorted estimate of the latent clear image. To tackle this issue, this paper presents an innovative single-image deblurring method. It integrates a dedicated blur kernel deblurring step to mitigate the effects of the denoising filter. The L0 norm and L2 norm serve as the respective constraints for latent clear image and blur kernel. Experimental results on both synthetic and real-world turbulence-degraded images demonstrate the effectiveness and efficiency of the proposed method.
