Abstract
At propagation of a light field through atmosphere it is exposed to turbulent distortions. For reduction of their influence adaptive optical systems (AOS) are used. One of the important problems in work AOS is its speed limited to action of the correcting mirror. Here proposed the methods to reduce the influence of delay system on the accuracy of its work. Carried out the comparative analysis of accuracy of definition of centroids coordinates for the cameras, built on the basis of CCD and CMOS technologies. Considered modes instantaneous sampling and frame-by-frame accumulation of the information from the camera. Results of numerical experiments are presented.
