Wave front aberration compensation of spacecraft telescopes with telescope temperature field adjustment

Abstract

A technique of wave front aberration compensation for space telescopes is considered. According to the technique introduced, first, point spread functions (PSF) for the range of temperature field parameters and mirrors displacements are calculated. Then, the calculated PSF closest to the measured one is assumed as a base for the optimization procedure, according to which a set of the parameters most precisely approximating the measured PSF is obtained.
