Solid-state color imager with stripe or mosaic filters
Abstract:
A solid-state color imager comprised of a solid-state base comprised of a plurality of charge switching elements said base further including photodiode elements associated with some of the switching elements arranged in sets having superimposed thereon a photosensor layer comprised of photoconductor segments which can detect and absorb light. A plurality of mono colored stripe filters are superimposed over the photosensitive layer. The 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 filter stripes, light of a particular color is absorbed. The unabsorbed light continues to travel and strike the photosensor layer whereat another color of light is absorbed and detected. The unabsorbed light passing through the photosensor layer and perhaps a stripe filter, strikes the photodiode elements of the base which detect the remaining light. The photosensor layer is electrically insulated from the base and in connection with the photodiode elements of the base and filter stripes, make possible detection of three separate colors of light such as blue, green and red without the use of multi-color filter arrays.
