Abstract
The control algorithm for adaptive optics system, which works using focal spot of the light beam, is proposed. Algorithm is based on the analytical relationship between spot-radius and the changing of the deformable mirror surface. A numerical modeling, which confirms this dependence and the opportunity of its usage for wave front correction, has been carried out. Some experimental results that point out the opportunity of using the algorithm in practice have been presented.
