Complex matrix manipulation in optical computing. a 4F system. Two gray bars represent input data (A) and convolution results (C). The convex lens is Fourier lens that implements Fourier transform. The orange bar represents a matrix. b Schematic of optical convolution processor based on dispersion effect. c Schematic of diffractive deep neural networks with multi-layers of passive diffractive planes
