Paper Abstract

An effect of anisoplanarity is caused by difference of aberrations on paths of the direct and reference beams. These differences are due to variances of path geometric characteristics (different angles or divergence) or due to the presence of temporal lag. In many cases the causes of these factors are similar, moreover, methods of their mathematical representations are similar too. Next factor limiting the possibility to use adaptive correction for turbulent aberrations is fast motion of an object. This imposes strict conditions on the rate of adaptive control and on the power of a Rayleigh beacon.
