Abstract : Photoconductive semiconductor material is injected into narrow and closely spaced cylindrical channels in an insulating matrix plate to form pixel elements of a high resolution photodetector array. A transparent conductive layer is deposited on one surface of the photoconductor array while light reflecting pads are formed on the elements at the opposite surface. Subsequently, a layer of light modulating material and a transparent conductive layer are deposited on the opposite surface to obtain a high resolution spatial light modulator. (KAR) P.1
