The principle of the adaptive optics system for all-path aberration correction was analyzed in detail according to the theory of wavefront propagating in optics medium. While the wavefront sensor was calibrated by conventional method, the residual error of the adaptive optics system was deduced, and the shortcoming was indicated from the points of the residual error and the operation feasibility. Based on the characteristics of the adaptive optics system for all-path aberration correction, two kinds of new calibration methods for common mode Hartmann wavefront sensor were proposed, and the residual error of the system was analyzed in detail while the wavefront sensor was calibrated by new methods. The result indicates that the residual error of the system calibrated by the two new calibration methods is related to one of the residual errors of the system calibrated by the conventional calibration method.
