Abstract

The performance characteristics of three unique optically-addressed spatial light modulator (SLM) structures have been experimentally investigated. The measured parameters include 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 a well established industry benchmark, the Hughes Liquid Crystal Light Valve (LCLV). A comparison of these devices in terms of the above performance parameters is discussed in this communication.
