Abstract: A sandwich structure of photosensitive junctions in series with a mosaic of photoemitters. An external grid is positioned adjacent the mosaic of photoemitters and has the high voltage side of a step up voltage divider thereto with the low voltage side connected to the input side of the sandwich structure. The sandwich structure and external grid are enclosed in a vacuum envelope for converting an input optical radiant image into an electron image for display on an electroluminescent screen. A bias light is uniformly flooded over the mosaic of photoemitters to provide saturation electron current therefrom. The flow of electrons emitted from the photoemitters are in proportion to the intensity of infrared light incident on the input side of the sandwich structure. The input side of the structure has an antireflection coating thereof for aiding the incident infrared light in producing electron-hole pairs across the photosensitive junctions.
