Abstract

The Shaсk-Hartmann wave front sensor measures the coordinates of the energy centers of gravity of the focal spots located in the plane of the receiving device in the form of the Shack-Hartmann pattern. The Shack-Hartmann pattern can be definite and not fully defined, i.e. on it there can be no separate focal stains or groups of focal spots. The information extracted from such Shack-Hartmann patterns change significantly the result of the wave front reconstruction. This suggests also the creation of a modification of the previously developed correlation algorithm for calculating the speed of transverse wind transfer of the turbulence. The results of numerical studies are presented.
