Abstract

A prototype of a key element of adaptive-optical systems - a controlled flat mirror used to correct light beam tilts - was designed. An algorithm for correcting atmospheric distortions of low-intensity light waves and real-time software were developed. In laboratory experiments, a bandwidth of the closed system of 100 Hz was achieved. The efficiency of the developed software was confirmed by daytime observations of stars.
