FIELD: remote sounding of the Earth in the interests of national economy and for solving of special problems. SUBSTANCE: space reflecting-refracting telescope is used on spacecraft. It includes primary and secondary mirrors, lens field corrector, collecting lens, converter of focal distance and opticoelectron converters manufactured in the form of set of linear or matrix photodetectors located in focal plane. Peculiarity of invention lies in manufacture of converter of focal distance in the form of matrix of lenses positioned in staggered order. Axes of lenses in this case are parallel to major optical axis of telescope and their magnification is equal to number of rows in matrix. Telescope is also fitted with image synchronization unit which inputs are connected to outputs of opticoelectron converters. EFFECT: reduced mass of telescope. 3 dwg
