When optical microscopy meets all-optical analog computing: A brief review

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