Abstract

An amorphous silicon photoconductor has been demonstrated in a reflection mode nematic field effect liquid crystal spatial light modulator. The thin-film photoconductor provided high resolution of >35 lp/mm and sensitivity better than 20 μW/cm². In addition the switching speed was liquid crystal limited. Reported are the performance characteristics as well as a theoretical model for the device.
