Abstract

The coherent light valve is a video-input spatial light modulator developed for real-time optical processing. It was developed as a modified form of the commercial GE light valve TV projection system. The video input signal phase modulates the optical aperture by modulating a raster-scanned electron beam. At compatible TV rates (525/30) the CLV system has a bandwidth of 10-15 MHz and a dynamic range of 40 dB or more . Higher scan rates have demonstrated bandwidths up to 100 MHz, and a special CLV tube design can operate above 100 MHz. Recently compact rack-mounted processor configurations, suitable for user environments, have been developed. This paper reviews past and present work and offers some predictions regarding future developments of the CLV system.
