title: Analog nonvolatile optically addressed spatial light modulator.
abstract: We present a nonvolatile optically addressed spatial light modulator for use in optical processing and projection systems. The device utilizes the spatial nonvolatile switching of a ferroelectric liquid crystal addressed through a photoconducting medium. One obtains an analog representation similar to halftone printing by threshold switching of micro-optically modified pixel intensity profiles. An experimental demonstration of the device is described, together with qualitative and theoretical interpretation of the results.
