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.
