Phase-Modulated Optical System With Sparse Representation for Information Encoding and Authentication
We develop a phase-modulated optical system with sparse representation for information encoding and authentication. The optical cryptosystem is developed with cascaded phase-only masks, and the plaintext is encoded into the cascaded phase-only masks based on an iterative phase retrieval algorithm du...
