Abstract

In one voltage-driven embodiment, a high spatial resolution two-dimensional array of bistable completely cross-talk free light modulation elements is constituted as a lamination of an input two-dimensional photoconductor thin film layer and an output two-dimensional electroluminescent phosphor thin film layer disposed in etched wells individually defined in corresponding cores of the optical fibers of a fiber optic face plate. In another voltage-driven embodiment, a very low cost high spatial resolution 2-D array of bistable substantially cross-talk free light modulation elements is constituted as a lamination of a photoconductor thin film layer, a selectively dimensioned and apertured opaque masking thin film layer, and an electroluminescent phosphor thin film layer. In an electron-driven embodiment, a high spatial resolution two-dimensional array of substantially cross-talk free bistable light modulating elements is constituted as an assembly of a two-dimensional input window having a deposited photocathode thin film layer, a two-dimensional output window having a deposited cathodoluminescent phosphor, and a two-dimensional glass capillary array defining plural charge feed forwar…
