斑点掩模法能有效地消除地球大气湍流的严重干扰，实现天文目标的望远镜衍射受限分辨率复原，而傅里叶相位谱的复原是核心和难点。讨论了在微机上实现由重谱复原目标相位谱时所面临的实际问题：巨大的重谱信息量和计算机有限存储空间的矛盾；递推相位区域和路径；相位缠绕和误差积累等。给出了相应的解决方法对天文目标进行像复原的实验结果。 The speckle mask method can effectively eliminate the serious disturbance of the earth’s atmospheric turbulence and realize the resolution restoration of the astronomical telescope diffraction limited resolution. The recovery of the Fourier phase spectrum is the core and difficult point. The practical problems of reconstructing the target phase spectrum from the heavy spectrum are discussed in the computer: the contradiction between the huge heavy spectrum information and the computer limited storage space; the recursive phase region and path; the phase winding and the error accumulation. The corresponding solutions are given to experiment on the astronomical objects like restoration.
