Design of storage light intensifier panels

Storage light intensifier panels having an image resolution of 1275 elements per square inch were constructed. In these panels the bistable storage principle is applied to solid-state light amplifiers. Image elements are optically and electrically separated from neighboring elements. In the first two designs described the layer containing the photoconductor power is divided into cells while the electroluminescent layer is continuous. In one structure the photoconductor is put into holes in a transparent insulator. The holes are separated optically by an opaque mesh. The structures are made of Corning´s Fotoform glass which can be darkened or made etchable by photographic means. In another structure the photoconductor is in the form of a thick mesh surrounding transparent insulating pillars. A conducting mesh at the bases of the pillars is one electrode of the structure. Transparent conductor tops on the pedestals make contact to the electroluminescent layer.
