Abstract
This paper is devoted to the application of the phase conjugation meth od to thermal blooming compensation. Analysis of the numerical experim ental data has shown that the appearance of continuous auto-oscillatio ns in adaptive systems is connected with the occurrence of dislocation s in the reference beam. The use of the Hartmann sensor with low spati al resolution and modal estimation of the phase results in smoothing o f the phase estimate and damps the AOS oscillations.
