Abstract

In this review an overview will be given of the state-of-the-art in phase retrieval (PR). PR occurs in many different areas of signal processing: - in imaging, where the image only yields the modulus of the wavefunction in the image plane, while for the reconstruction of the object we also need its phase - in speckle interferometry where we obtain the modulus of the Fourier transform of the object wavefunction, while its phase cannot be determined - in interferometry where often only the modulus of the coherence function of the source can be determined.
