Abstract

A television camera tube having a discrete structure of photosensitive elements provided on an electrically conductive carrier covered entirely with photoconductive material or another resistance material, so that with a suitable potential applied to the carrier a potential distribution occurs having successive saddle points for the scanning beam. Variation and exposure of the discrete photoconductive elements then results in a variation in beam splitting in the saddle points, as a result of which the tube has a greater or smaller extent of natural amplification.
