IMAGE CONVERTER Russian patent published in 1997 - IPC

FIELD: optoelectronics, serves for processing of video information, applicable in computer engineering as an optically controlled device for information input to a computer. SUBSTANCE: the image converter, having an input transparent conducting electrode, photosensitive semiconductor, interference filter, electrooptic crystal and an output transparent conducting electrode, uses also an active high-resistance resistive layer possessing a volt-ampere characteristic with a negative incremental resistance and positioned between the photosensitive semiconductor and the interference filter; a thin-film heater is introduced in the active high-resistance resistive layer. EFFECT: improved design. 2 cl, 3 dwg
