Paper Abstract

An implementation of a phase extractor Vander-Lugt correlator, which operates with a single spatial light modulator is suggested. Optical phase-retrieval manipulation, based on the symmetrization of the input scenes is proposed. As a consequence, the number of digital manipulations of the information is substantially reduced and spatial correlation filters can be used. Theoretical analysis and some simulated results are provided. The study also includes the results when the scenes are immersed into background or zero mean additive noise.
