本文讨论了一般的非么正变换系统中二维波场分布的相位恢复问题。利用我们所建立的迭代算法,以一个具有衍射损耗的光学系统作为模型,对五个二维象差函数进行了重构相位的计算。在迭代的初始估计为随机分布的情况下,通过100—200次迭代,得到了满意的相位恢复解。The two-dimensional phase retrieval problem involving a non-unitary transform system with liffraction loss has been discussed. By means of our iterative algorithm, the phase distributions of five aberration functions have been recovered with the random distributions as initial input. The phase solutions agree with the true phases perfectly even though a heavy diffraction loss exists.
