Abstract

A first order theoretical model of a thin nematic liquid crystal layer mated to a CdS/CdTe heterojunction photosensor is presented. Uniform parallel alignment of the liquid crystal molecules with the light valve substrates is assumed. The response of the liquid crystals is predicted through minimization of the distortion free energy density and the operation of the photosensor is obtained by assuming it to be a back biased light activated charge storage diode. Measurements of an actual liquid crystal light valve response are presented to verify the model.
