Abstract
For studies of algorithms for stabilizing laser radiation during propagation in a randomly inhomogeneous medium, the problem of emulating atmospheric turbulence with the condition of repeatability of atmospheric parameters becomes topical. The second problem is to increase the speed and accuracy of the adaptive optical system by minimizing the error that occurs due to the displacement of the recorded beam image at the input aperture of the system during the time between frames caused by the turbulent atmosphere. A description is given of the stand of an adaptive optical system operating in the mode of emulating the tilts of the laser radiation wave front on a turbulent path with an additional loop for advanced correction of the beam tilt angle error due to the delay of the correcting Tip-Tilt mirror.
