Abstract
A solid-state color imager comprised of a solid-state base comprised of a plurality of electrical switching elements said base further including photosensitive elements associated with some of the switching elements arranged in sets having superimposed thereon a plurality of photosensor layers which can detect and absorb different colors of light. Each photosensitive layer is comprised of an upper transparent continuous electrode sublayer, a photoconductive sublayer, and a back mosaic transparent electrode sublayer which is electrically connected to said base. When light strikes the outermost photosensitive layer, light of a particular color is absorbed, and in connection with said base, its presence is electrically detected and recorded. The unabsorbed light continues to travel and strike the next succeeding photosensor layer whereat another color of light is absorbed and detected. The unabsorbed light passing through the second photosensor layer strikes the photosensitive elements of the base which detect the remaining light. The photosensor layers are electrically insulated from each other and the base and in connection with the photosensitive elements of the base make possible …
