Anisoplanatism error for the low-order mode and its influence on compensation effects are analyzed both theoretically and experimentally. For non-Kolmogorov turbulence, the anisoplanatism error, the angular correlation function of Zernike polynomials, the long-exposure optical transfer function (OTF), and the residual phase structure function are all discussed. The modal correction coefficient is used to evaluate the influence of anisoplanatism error on the compensation effectiveness of an adaptive optics system used as the low-order mode correction. The numerical calculation results of the modal correction coefficient and long-exposure OTF for light beam horizontal atmospheric propagation are also presented.
