Opto-electronic determination of binary phase-only filters for optical correlation

Thomas Heinrich Barnes

Abstract

A simple optoelectronic system for high-speed determination of binary phase-only filters for use in an optical correlator is described. Filters determined using the system were implemented using a liquid crystal spatial light modulator in the Fourier plane of an optical correlator. Results demonstrating the operation of the system are presented.
