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.

Keywords:

adaptive optics, deformable mirror, atmospheric turbulence, Shack–Hartmann wavefront sensor
