Abstract
Some last ten years the problem of compensation for dynamic distortions of primary mirrors in low-weight large-size imaging telescopes by methods of dynamic holography is actively being investigated. Today the performance of such systems has been experimentally proved. Thus, the idea to use in such a telescopic system a low-weight-film primary mirror, which can, in principle, be of large diameter in an unfolded mode, is very attractive one. In this paper the problems are considered related to integration of a thin- film primary mirror in a telescope with a non-linear corrector for an object image. Namely, there will be discussed the architecture of the telescope with the thin- film primary, optical quality of the mirror, requirements on the non-linear corrector, the telescope's field of view, and quality of the image of an object.
