FIELD: optoelectronic engineering, in particular, devices for focusing, optical filtration and conversion of received optical radiation to an electric signal. ^ SUBSTANCE: the optical system additionally has an edge filter of infra-red and ultra-violet radiation bands with a shutter and photodetector. The elements of the catadioptic lens are positioned on the gyroscope. The shutter is made of a disk of heat-resistant, nontransparent, nonmagnetic material with cut-outs of larger dimensions of the edge filters and positioned in the open position opposite them. The edge filter is made of a disk of heat-resistant, nontransparent, nonmagnetic material with inserts of materials conducting radiation in spectral regions within 0.019 to 0.022 mum and 2 to 3 mum located in an L-shaped manner. The wide-band photodetector represents an open-type photodiode with a sensitivity in the spectral region within 0.015 to 4 mum. ^ EFFECT: enhanced accuracy of processing of the optical signal at ranges to the target of less than 7000 m due to enhanced resolution of signal reception in the ultra-violet band. ^ 4 dwg |
