Abstract

The results of experiments carried out on the installation of a fast adaptive optical system with a bandwidth of 1500 Hz are presented. Graphs of the spectral power and normalized energy of Shack-Hartmann wavefront sensor focal spot fluctuations are presented. Theoretical calculations and experimental data are compared. It is shown that in order to achieve a satisfactory correction of distortions caused by turbulence, the system operation frequency should be an order of magnitude higher than the maximum frequency of turbulent distortions.
