Spatial light modulators (SLM) are examined from the viewpoint of miniaturization and optical correlation systems. The structure and behavior of a silicon-chip active-matrix-addressed ferroelectric liquid-crystal SLM is presented. The response of an amorphous-silicon optically addressed nematic liquid crystal SLM is reported.
