Abstract: This invention is directed to improved photoactivated liquid crystal light valves or cells which exhibit extended lifetime. All electrically conductive elements of the light valve are separated from the liquid crystal layer by insulating layers. By thus separating all electrically conductive elements from direct contact with the liquid crystal layer, the life of the liquid crystal is significantly extended. To accomplish photoactivation in the presence of electrical insulating layers, the principle of impedance matching is applied to the photoconductor/liquid crystal combination. Three novel means of impedance matching are taught: 1) photoresponsive heterojunction; 2) low impedance liquid crystal; 3) metal grid.

Abstract: The optical processor employs a photoconductor-activated liquid crystal as a spatial filter to control transmissivity of coherent light through the processor. The liquid crystal filter pattern determines the pattern input to Fourier transform and can optionally also define the transmissivity of a Fourier processing filter. This permits near real time transform.
