SCANNER Russian patent published in 1995 - IPC

FIELD: optoelectronics. SUBSTANCE: invention refers mainly to infrared images. Scanner has telescopic system, scanning device, photodetector with objective and pair of flat mirrors inclined to axis and placed on both sides or on one side of objective of telescopic system. Radiation flux from object is directed to strip of photodetector 8 by two parallel branches. With rotation of scanning device 6 image of strip is transformed into invisible image of circular raster. In case of sufficient distance from object plane influence of parallax on quality of image can be ignored thanks to presence of base between sections of optical axis. EFFECT: enhanced operational reliability. 5 cl, 2 dwg
