Broadband and parallel multiple-order optical spatial differentiation enabled by Bessel vortex modulated metalens

Abstract Optical analog image processing technology is expected to provide an effective solution for high-throughput and real-time data processing with low power consumption. In various operations, optical spatial differential operations are essential in edge extraction, data compression, and featur...
