Abstract

Spatial light modulators (SLM’s) consisting of a polymer-dispersed liquid crystal (PDLC) film and a Bi12SiO20 photoconductor are discussed and demonstrated. This device, which uses light scattering in the PDLC film, has several advantages including no polarizer, a low optical loss, and video-rate operation. The device was designed by use of an electrical-image method. High-definition SLM’s with a limiting resolution (36-50 line pairs/mm) were fabricated by stacking of an optimized mirror and the PDLC film. The device, which was incorporated into a Schlieren system with a 1-kW xenon lamp, provided highcontrast video images and a total luminous flux of 1000 lm.
