Dependence of the effectiveness of multichannel radiation turbulent distortion compensation on the method of phase control: Increase of efficiency with amplitude control

Resumo

Numerical experimental results characterizing the propagation of multichannel laser radiation in the atmosphere are presented and the possibility of compensating turbulent distortions by use of phase control is considered. It is shown that the effectiveness of adaptive correction depends on the number of channels in the system and on the accuracy of the reference radiation phase reconstruction. The effectiveness can be additionally increased by gain control in each of the channels, i.e., by passing to amplitude-phase control.
