Abstract:

The adaptive system provides the correction of turbulent distortions, which have been defined during the previous moment of time, but changes to the time of their correction by the system. The forestalling adaptive correction allows setting the surface profile of a working mirror corresponding to the wave front on the entrance aperture of adaptive system for the future moment of time on the basis of last measurement of the Shack-Hartmann wave front sensor. Ways of forestalling formation of the profile of the correcting mirror are presented.
