Abstract
To study specific features of stabilization of optical radiation in a turbulent atmosphere, a model of jitter of the image formed by radiation in the focal plane is created. The image is characterized by wavefront slopes. Approaches to modeling the wavefront slopes and methods for estimating the image formed by radiation in the focal plane of the recording device are outlined. Statistical studies include the calculation of the coordinates of the energy center of gravity of the focal spot by various algorithms depending on the parameters of a random phase screen that defines turbulent inhomogeneities, their intensities, and locations on the radiation propagation path. The results of experiments on stabilization of optical radiation on the stand of an adaptive optics system are presented.
