An optical image transformation and encryption scheme is proposed based on double random-phase encoding (DRPE) and compressive ghost imaging (CGI) techniques. In this scheme, a secret image is first transformed into a binary image with the phase-retrieval-based DRPE technique, and then encoded by a series of random amplitude patterns according to the ghost imaging (GI) principle. Compressive sensing,...
Ghost imaging has become increasingly popular in quantum and optical application fields. In this work, we describe a multiple-object ghost imaging arrangement based on the computational framework. In this configuration, all the wavefronts of the object beams respectively interacting with the targets are collected together by only a single-pixel (bucket) detector, but any one of these objects can be...
