Optical sensing system for detecting and storing the position of a point source target

摘要: The position of a point source target in field view is simultaneously focused onto plurality sensing units by means multifaceted lens. Each the has photosensitive area which divided into pair equal elements are arranged either horizontal or vertical finger patterns. patterns binary coded fashion and at any particular time one other each unit generates an output response to optical target, combination such outputs being indicative target. fed digital registers develop signal for utilization readout device.
