Abstract

The results of experimental works on creation of the closed-loop adaptive optical system intended for the tip-tilt wavefront correction have been described. The control unit with a high-speed microcontroller realizing the management by piezo-electrical stacked actuators of the tip-tilt corrector with the help of stochastic parallel gradient algorithm has been developed. The results of experiments on the dynamic wavefront tip-tilt correction at the system bandwidth of 2 kHz are reported. The basic characteristics of the closed-loop adaptive system are measured.
