Abstract
A feature of adaptive optics systems is that measurements, control and correction of distortions of optical radiation should be carried out in real time. This is ensured by introducing into the optoelectronic system such elements as a wavefront sensor, a wavefront distortion corrector, and a data processing system for reconstructing the wavefront from measurements and calculating control actions for the corrector. The main distorting factor for most optoelectronic systems is atmospheric turbulence. Therefore, systems for atmospheric applications are developed individually, taking into account the turbulent characteristics of the atmosphere at the telescope's standing point. In this paper, we analyze the influence of the telescope in the adaptive optics system on the parameters of the Shack-Hartmann wavefront sensor.
