Implementation Features of Invariant Optical Correlator Based on Amplitude LC SLM
© 2020, Allerton Press, Inc.Abstract: Mathematical simulations of invariant optical-digital correlator operation are performed with the LC SLM used for the input images display and for display of the correlation filter holograms. Different phase dependences on amplitude are considered, particularly the measured dependence of the LC SLM HoloEye LC 2002. A method for optimization of correlation filters to eliminate the object recognition error due to the presence of additional phase modulation is proposed.

Features of the Implementation of Holographic Invariant Correlation Filters Based on a Phase Liquid-Crystal Space-Time Light Modulator
© 2019, Allerton Press, Inc.A method for implementing invariant correlation filters in the form of holographic filters in the design of an optical-digital image correlator using a phase liquid-crystal space-time modulator is considered. The results of the simulation of correlation recognition of half-tone images using holographic correlation filters are presented. The results of the experimental implementation of holographic correlation filters using a phase liquid-crystal space-time light modulator are also described.
