Abstract
Real time and reusable coherent spatial light modulators for use in optical data processing are summarized. The status of the six leading candidate real time devices that have seen use in coherent light are included. Three electron beam addressed devices are described (the dielectric oil film valve, the thermoplastic optical phase recorder, and electron beam DKDP). Three optically addressed spatial light modulators are also included (the liquid crystal lightvalve, the PROM, and photo DKDP). The operation, specifications, applications, and remarks on directions for future research are included for all of these devices.© (1977) COPYRIGHT SPIE--The International Society for Optical Engineering.
