Abstract

Most 8 - 12 micron infrared imaging optical systems consist of a telescope, angular scanner for parallel beams (polygon or nodding mirror type) and a detector lens. The telescope for all magnification modes, and the detector lens system, each one separately, have to be designed close to their diffraction limit over all scanned FOV to withstand the severe resolution requirements of the entire IR system. This fact mandates several aspherical surfaces for the telescope and the detector lens systems, for purposes of residual aberration correction. This paper describes an 8 - 12 micron FLIR in which, owing to the proposed lateral scanner for converging beams, the optical system is reduced to an objective only attached to the proposed lateral scanner which fulfills lateral scanning of the scenery image in the detector plane.
