Abstract
To calculate the control signals of a piezoceramic deflector when measuring the angles of arrival of optical radiation transmitted through atmospheric turbulence, various methods for estimating the beam image in the focal plane of the recording device can be used. The results of numerical studies of the accuracy of calculating the energy center of gravity of an image in the focal plane in several different ways are presented. These methods are used both in split photodetectors and in the Shaсk-Hartmann wavefront sensors.
