中文摘要	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。
英文摘要	The serious disturb caused by atmosphere turbulence can be eliminated effectively and the astronomical image reconstruction with the diffraction-limited resoluiton of the telescope can be achieved by the spectrum masking. The key problem is to recover Fourier phase spectrum. Some actual problems that will be faced when to recover object phase spectrum from the bispectrum with a micro-computer are discussed, including the huge info rmation of the bispectrum contradict the limited storage space of the micro-computer; the area and the path of phase recurring; phase wrapping and error accumulating in phase retrieving from the bispectrum. The corresponding methods used to solve these problems and the experimental result of image reconstruction for astronomical objects are given respectivly.
