Abstract
A mathematical model of an adaptive optics system was described in the article. The model included two main components: the model of an adaptive mirror and model of beam propagation under conditions of thermal blooming. Results of numerical simulation of adaptive optics systems were compared with data of laboratory experiments. High reliability of the model was shown.
Highlights
Adaptive optics systems are extensively used nowadays to correct distortions of laser beams propagating on atmospheric paths [1]
Beam propagating in the atmosphere suffers from random variations of the index of refraction and from thermal distortions induced by heating of the medium
In adaptive systems the information about distortions transmitted by the loop to the active element which forms a phase profile of the beam according the algorithm of correction
