Paper Abstract

The development of a reflection mode nematic field effect a � Si:H LCLV is described. The amor-phous silicon photoconductor layer is deposited by glow discharge without doping. The configuration al-so consists of dielectric mirror as CdS LCLVs do. The bias frequency is in the range of 500Hz to 10KHz. MTF, sensitivity and time response of the device are measured. High resolution of > 501p/mm and switching time less than 25ms are achieved. Also reported is an equivalent circuit mode which has been compared with experimental results.
