The wave superposition model of the geometric phase shows how the addition of waves creates a shift in the resulting wave position. While previous work focused on a basis of linearly polarized light waves and the Pancharatnam-Berry phase, w...

This paper presents a unified analytical framework to derive the three-dimensional transfer characteristics of axially symmetric optical imaging systems operating in the far field, with emphasis on coherence scanning interferometry, confoca...
Framework for noise-type and noise-level estimation under additive and multiplicative models in color images [0.03%]
加性和乘性模型下的彩色图像噪声类型和噪声水平估计框架

Zipeng Fu et al.
Accurate estimation of the noise type and noise level in color images is crucial for tasks such as denoising, segmentation, and super-resolution. However, existing approaches often rely on the assumption that the noise type is known, and th...
Physics-informed deep learning framework for wavefront sensing via optical beam pattern analysis [0.03%]
基于光学光束模式分析的物理信息深度学习波前传感框架

Tengfei Chai et al.
We propose PIRNet, a lightweight, physics-informed deep learning framework for non-interferometric wavefront sensing in optical beam expansion systems. The network simultaneously estimates spherical aberration, coma, and astigmatism from si...
Adaptively balanced Poisson-constrained physics-informed neural networks for robust displacement integration in background-oriented Schlieren [0.03%]

High-dimensional quantum key distribution (HD-QKD) is limited by atmospheric turbulence, which scrambles the spatial modes used to encode information. A critical challenge is the lack of general methods to diagnose how this decoherence occu...
Reflection in a concave spherical mirror-two contrasting conceptions of optics: retrospective [0.03%]
凹面球彎境中的反射：两种对立的光学观念之回顾
Yaakov Zik,Giora Hon
Yaakov Zik
We contrast two approaches to the optics of reflection in concave spherical mirrors. In the Optics (ca. 165), Ptolemy employed the cathetus principle as a regulative rule to account qualitatively for visual appearance in concave spherical m...
