Paper Abstract

The spatial analysis of the wavefront distortions registered by the Shack-Hartmann sensor of the adaptive optics (AO) system of Large solar vacuum telescope have been performed. In the paper the results of analysis of spatial structure of the wavefront within the field of view ~35 arcsec are discussed. It is shown that the wavefront distortions formed within the field of view ~35 arcsec are not random. There are the repetitive hills of spatial crosscorrelation functions in the field of view at the same intervals for different space subapertures. It is shown that spatial crosscorrelation functions do not contain pronounced kernel for finding the exact position of the atmospheric layer contributing to significant distortions in the wavefront incident on the telescope aperture.
