Popis: The temporal error is the main problem for adaptive optical systems operating in the atmosphere. One way to solve this problem is to optimize the adaptive optics system by predictive control algorithms. In study the adaptive optical system installed on the small-aperture telescope with the predictive algorithm are developed. The predictive algorithm uses measurement of center gravity of light intensity at subapertures of the Shack-Hartmann wavefront sensor has been developed. In results it not depends on the type and design of the adaptive mirror. For implementation the Shack- Hartmann wavefront sensor measuring phase distortion, atmospheric turbulence, and transverse wind velocity are created. The design of the wavefront sensor allows replacement of the microlens array with different sizes, focal lengths and operated in wide range of phase aberrations. As a result, the adaptive optics system measure the level of optical atmospheric turbulence for replace the microlens array and it to operated in different turbulent atmospheric conditions.
