Characteristics of a ferroelectric liquid crystal spatial light modulator with a dielectric mirror

The continuous gray scale operating characteristics of a ferroelectric liquid crystal spatial light modulator (FLC-SLM) are described. Then an FLC-SLM having a dielectric mirror between an a-Si:H photoconductor and an FLC light modulatory material is presented, and its operating characteristics are reported. The FLC-SLM having a dielectric mirror allows for continuous gray scale applications. It exhibits a resolution of 80 to 100 lp/mm and a higher optical gain than the device without a dielectric mirror.
