A study on reconstruction of the object functi on from Fourier power spectrum
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 reconstructed from a single intensity measurement-the modulus of Fourier-transform. Precisely like 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 algoritiuns have bean compared in detail.
