ethod of generating a video data stream by rotary sectoral photoreceptor and device for its implementation // 2576336
FIELD: optics.SUBSTANCE: invention relates to video data flow formation Rotary sector photo receiver. Method is based on generation of signals from photosensitive elements installed on the area of the rotating sensor, their subsequent arrangement in the core of spatial differentiation, output signals which are subject to analogue-to-digital conversion and their further digital processing. Photosensitive elements are installed in series at equal distances between each other on arcs with discrete radii of Rmin to Rmax on the area of rotating sensor having the shape of a truncated sector range, which faces larger side to outer diameter of rotation. Photocurrents from photosensitive elements are amplified by DC and limit at frequency band depending on the sensitivity of photocells and sensor rotation frequency. Own noise minimises and corrects amplitude-frequency characteristics of signal transmission channel of each photosensitive element with subsequent formation of nuclei of spatial differentiation, signals from which are subjected to analog-digital conversion and subsequent digital processing.EFFECT: higher image quality.2 cl, 6 dwg
