| Abstract: | Phase retrieval problem is one of the most important projects in modern optics. Among many iterative methods, Fienup algorithm had made a great success. In present paper we describe a new method which has been demonstrated to be more practical than Fienup algorithm, by which an original object oan be reconstructedfrom a single intensity measurement-the modulus of Fourier-transform. Preciselylike Fienup algorithm, tha new algorithm is still an iterative Fourier-transform method, however, the con ergency of the new method is much faster than that of the previous method. The two-star model is adopted as the example of object function, and the calculation results obtained by using two different algorithms have been compared in detail. |
