Abstract
A prototype of a key element of adaptive-optics 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 value of 100 Hz was achieved for the bandwidth of a closed-loop system. The efficiency of the developed software was confirmed by daytime observations of stars.
