An Adaptive Fourier Optical Processor.

A prototype liquid-crystal-over-silicon spatial light modulator (SLM) with 16 x 16 pixels has been fabricated and used as an adaptive filter in the Fourier plane of a coherent optical processor. Preliminary results showing images of simple objects filtered through the SLM are presented. For comparison, images of the same objects obtained using photographic transparencies to simulate the action of the SLM as a filter are also presented.
