Numerical analysis of algorithms for centering the optical radiation image in the focal plane

In the problems of adaptive correction of distortions of radiation propagating in a turbulent atmosphere, as well as in problems of focusing laser radiation, the efficiency to a certain extent depends on the algorithm that estimates the radiation image in the plane of the receiving device. This paper presents the results of evaluating algorithms that determine the coordinates of the energy center of gravity of the focal spot within the recorded intensity distribution.
