Paper Abstract

One of the approach to calculate the characteristics of the air refractive index fluctuations along line of sight for multiconjugated adaptive optics is based on the triangulating the wavefront distortions or/and scintillation amplitudes analysis. The description of the experiments aimed to measurements of the wavefront distortions and scintillation fluctuations is given. The scheme for recovering the optical distortions (wavefront) at the different heights is discussed. The results of changes of the wavefront distortions measured by Shack-Hartmann sensor in the spaced regions of images are discussed. The results obtained may be used for estimation of the real amplitudes of the wavefront distortions in crossed optical beams at the different heights using such method as SDimm+[ 5].
