Television camera tube comprising mosaic of conductive regions separated by insulator from semiconductor plate

摘要

A television camera tube having a semiconductor target which on the side to be scanned by an electron beam comprises a mosaic of electrically conductive regions each determining a picture element and separated from the semiconductor plate by an electrically insulating layer, and a resistive layer extending over the mosaic and the insulating layer which contacts the semiconductor surface via an aperture in the insulating layer present in each picture element and has a RC time between the scanning time of a picture element and the scanning time of the whole target.
