Abstract
Created in Russian space observatory Millimetron with a 10-meter optical telescope has no analogues to solve scientific and technical tasks of research objects in the Universe. The amount of information that can be obtained at this observatory largely depends on the chosen concept and manufacturability of technical means that implement a high image quality in the telescope. The article, based on the analysis of distorting factors, examined ways of possible technical solutions and concepts, which can be the basis for the creation of systems of adaptive correction of the wavefront distortion (WF) of the received radiation. Variants of adaptive space telescope optical system are considered and analyzed. Following the results of analysis the adaptation at the entrance pupil of the telescope is selected and substantiated, are realized by a circuit of parallel information reading petals of the compound main telescope mirror.
