Abstract

Correction for turbulent distortions with an adaptive optics system including Shack-Hartmann sensor is considered in the paper. Efficiency of control was analyzed under conditions of singular points development in a wavefront of a laser beam. It was shown that the presence of dislocations causes the discrepancy of wavefront detection by the sensor and as a consequence leads to the control instabilities. It was also shown that dislocations appear mainly in the peripheral regions of the beam. Using this feature and optimizing the size of the sensor the stable adaptive control could be achieved in an adaptive optics system.
