Paper Abstract

Twisted-nematic liquid crystal televisions (LCTVs) are currently widely used as spatial light modulators in coherent optical processing systems. With such devices, `phase-' or `intensity-only' modulation is not easily achieved. In this paper we present procedures for finding some specific operating modes that can be achieved with these commercial LCTVs. The operating modes were found both by studying the Lu and Saleh model of LCTVs, and by referring to previous laboratory measurements. We will introduce a simple experimental procedure that can be used to locate a phase-mostly operating mode. The operating modes are considered in the context of a coherent optical correlator.
