Paper Abstract

The optical phase retrieval problem occurs in imaging, microscopy and several types of interferometry. This paper is concerned with retrieving an optimal estimate for the Fourier phase from a restricted number of noisy Fourier magnitude (or power spectrum) data samples. Of particular interest is the case when the direct Fourier transform of such limited data provides a poor object estimate even when the correct complex data are available. A method to achieve this is described based on the minimisation of a phase dependent cost function and the results of an approximate but sub-optimal iterative implementation are discussed.
