Abstract

Theory concerning the use of liquid crystal televisions as phase modulators in 4f correlators is presented. A computer simulation of a 4f correlator is presented. The simulation depicts the response of a 4f system to matched and phase-only filters calculated for amplitude- and phase-only inputs,
