Abstract
With the advent technology of the laser guide stars the problem of general tilt wave front correction appears. The high aberrations of the wave front are corrected by means of signal from laser guide star. However, whereas such star is formed by means of laser beam, directed from telescope, it can be represented as spherical wave with random center position. Residual distortions of high aberration phase fluctuations in such presentation with calculation in the Huigens–Fresnel’s approximation are executed.
