| Abstract: | In this paper, the compensation effects of Hartmann sub-aperture gradients in an adaptive optics (AO) system were analyzed. A kind of optimal-gradient reconstruction algorithm was deduced from normal least-square (LS) reconstruction algorithm by considering the statistical characteristics of disturbed wavefront and measurement noise. The optimal-gradient reconstruction algorithm is concise and effective in practice. The compensation effect and the stability were calculated in the condition of atmospheric turbulence. |
