Caption
Optical information transfer through random unknown diffusers using electronic encoding and diffractive decoding. (a) The workflow of the hybrid electronic-optical model: the electronic neural network encodes the input objects into 2D phase patterns and the all-optical diffractive neural network decodes the information transmitted through random, unknown phase diffusers. (b) Photograph of the 3D-printed diffractive decoder operating at THz part of the spectrum. (c) Experimental results of optical information transfer through an unknown random phase diffuser using the 3D-printed diffractive decoder with electronic encoding.
