SCANNING SYSTEM Russian patent published in 1995 - IPC

FIELD: optoelectronics. SUBSTANCE: invention relates mainly to infra-red imagers. Scanning system includes two-side mirror 1 set in case 6, objectives 2 and 3, photodetectors 4 and 5, convex 7 and 8 and concave 9 and 10 mirrors and flat mirrors 13 and 14 with holes. Scanning system makes it possible to enhance detection capability of its two channels by increase of scanning efficiency and by realization of simultaneous deviation of sighting beams of two channels within limits of chosen field. Radiation flux from object plane is directed to receivers 4 and 5 along parallel branches 13-9-7-1-3 and 14-10-8-1-2. Thanks to simultaneous action of two receivers detection capability of scanning system grows two times. EFFECT: two fold increase of detection capability of Scanning system. 3 cl, 3 dwg
