Abstract

Determination of misalignment contributions of the optical system induced by individual elements errors and optimisation of "coarse" and "fine" corrections are the main purposes of the present paper. Function of the system perfomance dependability is investigated by means of a model of the adaptive segmented mirror telescope. The problem solution is found based on wave aberrationsd minimizattion in accordance with the corrector displacements. Position displacements of the secondary mirror in relation to thed primary one as well as these of peripheral in relation to the central one seem to be parameters of this dependence. A correlation between these parameters and temperature fluctuation range is found for this optical module. Maximization of the said parameters weighted sum within the minimization problem solutions domain provides necessary conditions for correction process optimisation and determination of optimal aligment of the system main elements.
