The principle of the adaptive optics system for all-path aberration correction is presented. And the correction ability of the adaptive optics system for all-path aberration correction is confined by the aberration of the retro reflector array. Three kinds of the retro reflector arrays are numerically simulated for the appointed wavelength adaptive optics system for all-path aberration correction. It is studied that the aberration of the retro reflector array can be neglected while all-angle error of cell of the retro reflector array lies in 2＂. The simulation result is approved by the all-angle error based on the aberration of retro reflector in retro reflector array measured by WYKO interferometer.
