| 摘 要： | 假定大气湍流集中在两薄层内，借助分层大气相关长度与整个大气层相关长度的关系，给出待求相位分布与测量结果相关的超定方程组，进而构造残差方程组，并按最小二乘法原理导出正则方程组，通过求解这组正则方程，首次得到原超定方程组的最小二乘解。

| Abstract: | The multiconjugate correction should allow the field of view (FOV) of adaptive optics system increased significantly. This method implies a knowledge of the three dimensional OPD (optical path difference) distribution in the atmosphere. A simple atmosphere model is assumed in which the turbulence is concentrated in two layers. The relationship of the phase distribution between the measurement result and that to be determined has been presented. |
