We propose and discuss discrete recurrent algorithms for the retrieval of coherent light fields phase from measurement data of the intensity distribution of their spatial spectra. It is shown that the amplitude‐only and the phase‐only light fields are retrieved uniquely from the modules of their Fourier spectrum while, introducing in that fields the phase and amplitude masks respectively, satisfying certain conditions. Arbitrary amplitude‐phase light fields are retrieved from two modules measurements of their Fourier spectrum, namely, before and after introducing the amplitude‐phase masks.
