Abstract
Abstract A photosensitive array together with field effect transistors are coupled to the array''s columns for video coupling; Schottkybarrier diodes are connected to the rows for vertical decoding, and field effect transistors are connected to the columns for horizontal decoding, the vertical and horizontal decoders being activated in sequence by two pairs of different speed shift registers. The diodes and transistors are formed by thin film evaporation, the diodes having a cadmium sulfide-tellurium interface and the transistors using a cadmium-selenide semiconductor. Double gate field effect transistors can be used as combination decoders and video couplers.
