Phase Retrieval: An Overview of Recent Developments
In many physical measurement systems, one can only measure the power spectral density, i.e., the magnitudesquare of the Fourier transform of the underlying signal. For example, in an optical setting, detection devices like CCD cameras and photosensitive films cannot measure the phase of a light wave and instead measure the photon flux. In addition, at a large enough distance from the imaging pl...
