Possibilities of determining optimal conditions for laser beam focusing in a turbulent atmosphere on the basis of the analysis of target image distortions are analyzed. A series of metrics is considered, which characterize the efficiency of laser beam focusing and the target image quality. A correlation is found between metric fluctuations in the target and observation planes in a dynamically varying turbulent atmosphere in the case of aligned optical axes of the beam focusing and observing systems. As applied to wireless communications, it is shown from the analysis of object images (radiation detector) that the adaptive control of tilts of optical axis of only the transmitting laser system significantly increases the efficiency of data communications.
