FIELD: physics; optics.
SUBSTANCE: invention is related to optical-electronic instrument-making and may be used for visualisation of object image by their own thermal radiation. Scanning system comprises inlet lens, cylindrical mirror surface installed slantwise to optical axis of input lens so that its generatrix makes angle of 90° with its optical axis in the point of their crossing, scanning mirror installed so that it may rotate in relation to axis parallel to generatrix of cylindrical mirror surface, projection lens, microscanner, photodetector, inlet of which is connected to inlet of electronic unit for processing of signals and display of video information, additionally cylindrical lens and prism with three cylindrical facets are installed in back section of inlet lens. At that cylindrical mirror surface is the second facet of prism along with beams direction and is installed in the area of intermediate image of inlet lens and cylindrical lens.
EFFECT: higher image quality.
