Concurrent Image Differentiation and Integration Processings Enabled By Polarization-Multiplexed Metasurface (Laser Photonics Rev. 19(4)/2025)

Abstract

Toward Concurrent Processing

In article number 2400718, Peng Li and co-workers propose a metasurface-based optical image processor for performing multiple analog optical computing tasks simultaneously; this enables concurrent image differential and integral operations for edge enhancement and denoising at multiple visible wavelengths. This concurrent processing architecture paves a promising pathway towards multifunctional and higher-speed image processing for machine vision and biomedical imaging.
