Abstract
The hydrogenated amorphous silicon (a-Si:H) photoconductor and the nematic liquid crystal BDH-E44 combine to create a liquid crystal light valve (LCLV). The transmission of the readout light is determined by the voltage across the liquid crystal. When write light illuminates the current carrying photoconductor, the potential of each layer is rearranged through the photoconductor and liquid crystal.
