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.
