Comparison of Optically-Addressed Spatial Light Modulators

Abstract

The performance characteristics of three unique optically-addressed spatial light modulator (SLM) structures were investigated. The measured parameters included maximum resolution, visibility, imaging response time, and write light sensitivity. The modulators investigated include two relatively new technologies: the ferroelectric liquid crystal (FLC) SLM from the University of Colorado-Boulder and the amorphous silicon photoconductive twisted nematic liquid crystal SLM from GEC-Marconi Research, and the Hughes Liquid Crystal Light Valve (LCLV), which is a well established industry benchmark. This report is a compilation of the operating parameters and performance of these three modulators. Investigated parameters are conductive to understanding these modulators as input image transducers in optical correlator architectures.
