ABSTRACT:
A photosensitive matrix having a substrate with a group of row conductors, a group of column conductors extending across the row conductors to form a plurality of points of intersection with a photoconductive cell in series with a rectifier adjacent each point to inteconnect the row conductor to the column conductor characterized by the substrate being of a material which is at least approximately light impermeable in the light-sensitive spectrum of the photoconductive cells so that light projected on one cell is not conducted by the substrate to create a false signal in adjacent cells. Preferably, the substrate is a ceramic material which has been dyed black and the dyed black ceramic material consists of Al.sub.2 O.sub.3 mixed with Fe.sub.2 O.sub.3.
