This paper summarizes the theoretical and experimental results on the problems into the development and use of adaptive systems, obtained recently at the Laboratory of Applied and Adaptive Optics. A classification of up—to—date optoelectronic systems (OESs) is proposed as well as the place of the adaptive systems among OESs is shown. The problems of the adaptive systems evolution are underlined, i.e., developing of modern numerical models and performing of structural analysis of the most promising algorithms and loops of OESs with adaptive correction.
