Abstract

As a revolutionary observation tool in life science, biomedical, and material science, optical microscopy allows imaging of samples with high spatial resolution and a wide field of view. However, conventional microscopy methods are limited to single imaging and cannot accomplish real-time image processing. The edge detection, image enhancement and phase visualization schemes have attracted great interest with the rapid development of optical analog computing. The two main physical mechanisms that enable optical analog computing originate from two geometric phases: the spin-redirection Rytov-Vlasimirskii-Berry (RVB) phase and the Pancharatnam-Berry (PB) phase. Here, we review the basic principles and recent research progress of the RVB phase and PB phase based optical differentiators. Then we focus on the innovative and emerging applications of optical analog computing in microscopic imaging. Optical analog computing is accelerating the transformation of information processing from classical imaging to quantum techniques. Its intersection with optical microscopy opens opportunities for the development of versatile and compact optical microscopy systems.

当光学显微镜遇到全光学模拟计算:简要回顾
光学显微镜作为一种革命性的观察工具,在生命科学、生物医学和材料科学中,可以对样品进行高空间分辨率和宽视野的成像。然而,传统的显微镜方法仅限于单次成像,无法完成实时图像处理。随着光学模拟计算技术的迅速发展,边缘检测、图像增强和相位可视化等技术引起了人们的广泛关注。实现光学模拟计算的两个主要物理机制源于两个几何相位:自旋重定向Rytov-Vlasimirskii-Berry (RVB)相位和Pancharatnam-Berry (PB)相位。本文综述了基于RVB相位和PB相位的光学微分器的基本原理和最新研究进展。然后重点介绍了光学模拟计算在显微成像中的创新和新兴应用。光学模拟计算正在加速信息处理从经典成像技术向量子技术的转变。它与光学显微镜的交叉为开发多功能和紧凑的光学显微镜系统提供了机会。
