ABSTRACT:
An array of elemental electrodes, each electrode serving in a dual manner as a light sensitive source of photoelectrons, a primary photocathode, and as a collector of electrons for an auxiliary light sensitive input photocathode, followed by a pair of accelerating-retarding field grids and a light emitting phosphor screen to convert electrons passing the retarding field grid to a visible output image. An input optical image, to be processed, impinges on the primary photocathode, while a biasing flood light is provided to excite electrons from the auxiliary photocathode acting as a control on the level at which switching to visible output brightness occurs.
