Abstract
Fast adaptive system for atmospheric turbulence compensation working with a frequency of 200 Hz is presented in this paper. As a stacked actuator, deformable mirror with 97 piezoactuators and 2 kHz Shack–Hartmann wavefront sensor were used for adaptive system design. The dependence of residual correction error of the sine signal upon the time of the system reaction is also considered.
