Abstract

In order to realize a practical device, nonpixelized, optically addressed spatial light modulators, that is, a microchannel spatial light modulator (MSLM) and parallel aligned nematic liquid crystal spatial light modulator (PAL-SLM) have been developed. A large depth of phase only modulation based on the electro-optical characteristics of an electro-optic crystal and a liquid crystal layer have been obtained. For practical purposes, we have developed a nonpixelized, electrically addressed spatial light modulator such as electron beam addressed spatial light modulator (EBSLM) and LCD coupled PAL-SLM. We have also developed some applications by utilizing the features of these spatial light modulators.
