Abstract. Several issues of positioning of mirror elements of segmented primary telescope mirror are theoretically investigated. Criteria for the quality of segmented mirror depending on its surface shape are considered. An algorithm for mirror surface adaptation (positioning of composite mirror segments) is presented. The proposed control system for composite mirror makes it possible to control the spatial position of the mirror segments and position them.
Keywords: segmented mirror, mirror segment, adaptive optics, quality criteria, modulation transfer function
