DEVICE FOR IMAGE CONVERSION Russian patent published in 2000 - IPC

FIELD: optical information processing. SUBSTANCE: device provides integration of optical signal with respect to frame and its conversion into electric signal, which controls automatic regulation of voltage level, which supplies multiple-layer structure of image converter. Control optical signal is designed as either writing light E₀(x,y,Δλ) around frame with generation of surface integrated flow, or its fraction e₀(x,y,δλ), which is integrated by introduced mirror into small region between controlled electrodes, which are located outside of frame in order to generate surface or three-dimensional photo current. Conversion of control optical signal into electric control signal is achieved by means of high-resistance photo semiconductor, which is simultaneously used as substrate of multiple-layer structure for image conversion. EFFECT: increased functional capabilities, increased dynamic range of writing light intensity and optical density of converted image. 3 cl, 5 dwg
