Development of liquid crystal light valves using Bi12 Sio20 as the photoconductor. Part 1: Charge trapping and its effect on device resolution

The effect of charge trapping on the resolution of a liquid crystal light valve using bulk bismuth silicon oxide (Bi12SiO20) as the photoconductor has been analysed. The method of solution is to set up and solve the appropriate differential equations for the light valve geometry. The variation of sensitivity and resolution is examined as a function of symmetric and asymmetric charge location and spatial frequency.
