Spatial light modulators are a fundamental device in optical information processing and optical computing. We have developed a matrix addressed ferroelectric liquid crystal spatial light modulator (FLCSLM) with 64×64 pixels, the dimensions of each pixel are 80×80 (μm), its contrast ratio exceed 60:1 and the frame rate exceed 27 Hz. The driver of FLCSLM also has been manufactured. It enables the FLCSLM to realize display in video rate under the control of computer.
