本文提出了一种快速求解全波函数相位的算法，该全波函数在成象系统的衍射面和成象面中的强度是已知的。给出了一个证明，表明一个定义的估计函数和正确的函数之间的误差必须减少算法迭代。唯一性的问题进行了讨论，结果表明该方法的力量。
An algorithm is presented for the rapid solution of the phase of the complete wave function whose intensity in the diffraction and imaging planes of an imaging system are known. A proof is given showing that a defined error between the estimated function and the correct function must decrease as the algorithm iterates. The problem of uniqueness is discussed and results are presented demonstrating the power of the method.
