Image processing apparatus employing a spatial light modulator

摘要: An image processing apparatus comprises a liquid modulator having photoconductive material including an image-writing plane, crystal layer laminated on the material, pair of electrodes sandwiching and layer, spacer inserted between one electrodes. Also provided are analog writing system for analogously original in light modulator; digital reading digitally written section image-processing read data; processed data and, modulator. The is either phase-transition type crystal, p-type smectic A providing storage function, or ferroelectric function. selected from group consisting (1) cholesteric (2) mixture nematic crystal. chiral C non-chiral (3) photoactive material.
