OPTOELECTRONIC CAMERA FOR REMOTE EARTH SOUNDING Russian patent published in 2001 - IPC

FIELD: space flight vehicles for research of the earth surface in the interests of the national economy and for solution of special problems. SUBSTANCE: the optoelectronic camera has a common objective lens both for the panchromatic and multi-spectral channels. The catadioptric lens consists of the main and secondary mirrors, as well as of a lens field corrector. Optoelectronic transducers made in the form of a set of linear or matrix photodetectors are installed in the focal plane of the objective lens. The camera is also provided with a focal distance transducer, lengthening the focal distance, two collecting lenses, having the shape of a segment and located symmetrically relative to the optical axis in the direction of travel of optical rays past the lens field corrector, shortening the focal distance of the focal distance transducer, and a color separation unit installed past the focal distance transducer and having several channels, connected to whose outputs are additional optoelectronic transducers. EFFECT: enhanced functional capabilities of the chamber, reduced overall dimensions and mass of it. 1 dwg
