Abstract
One possible approach to determining the minimum set of parameters of an adaptive system whose operation is aimed at minimizing distortions arising in modern optoelectronic systems is considered. The basic source of distortions is assumed to be atmospheric turbulence, which imposes the most severe constraints on optical radiation in the atmosphere. The following basic parameters of the system are proposed: number of degrees of freedom, required frequency band (dynamic characteristic, and constraint on the spectral characteristics). Some parameters of the reference source (its size, position, and properties) are determined. The results are obtained in the form of analytical functions, which allows calculating the parameters of the adaptive system that can be used in numerous scenarios in the atmosphere.
