FIELD: optical instruments, in particular, scanning infrared devices. SUBSTANCE: device has telescope system, flat scanning mirror, spherical mirror, mirror multiple-face scanning drum which reflects outside, lens, photodetector and model of absolute black body, additional spherical mirror, which curvature center coincides with curvature center of main spherical mirror providing second telescope system. Curvature radius conforms to condition of R1/R2=0.5, where R1, R2 are curvature radiuses of additional and main spherical mirrors. In addition device has additional mirror drum which reflects inside and which number of faces differs from that at main mirror drum and which is mounted on same shaft as main mirror drum for rotation in same direction. Input eye of telescope system lies in same plane as curvature center of spherical mirrors which provide second telescope system. Vision axes of lens are crossed. Focal plane of lens contains sensitive areas of photodetector and scanning drums. EFFECT: increased functional capabilities. 4 dwg |
