Abstract
An adaptive optics system for correcting laser radiation distortions on a long atmospheric path in real time is presented, which includes an atmospheric turbulence emulation unit and a forward correction contour for errors in laser beam tilt angles caused by the delay of the correcting Tip-Tilt mirror. The forward correction algorithms are tested based on the numerical analysis of measurements performed by the Shack-Hartmann wavefront sensor.
