An adaptive optical system with independent compensation of random local wavefront tilts on four segments (sectors)of the aperture was modeled. The tilts were estimated from the shifts in the centers of gravity of the images formed by the corresponding segments of the aperture. The dependence of the resolution of the system on the ratio of the aperture diameter to the size of the region of correlation of the atmospheric distortions (Fried's parameter)is derived. It is shown that compensation of four local tilts makes it possible to obtain 1.9 times higher resolution than with the compensation of the overall wavefront tilt on the entire aperture.
