The phase diversity and the phase retrieval

SPIE Proceedings, 2015
Measuring optical wave-fronts precisely is a difficult task because detectors directly sense intensity, not phase. The most common method of measuring the phase uses an interferometer that creates an intensity distribution from which the phase of the field can be determined more easily.

Empirical Studies on Phase Retrieval

2018 IEEE 13th Image, Video, and Multidimensional Signal Processing Workshop (IVMSP), 2018
In phase retrieval, the signal is recovered from magnitude data that can be collected in various ways, ranging from the Fourier transform to general linear transform. Through experimental observation, we address the questions: (1) which sampling method, given the number of measurements versus signal size, best recovers the underlying signal?

Fast compressive phase retrieval

2015 49th Asilomar Conference on Signals, Systems and Computers, 2015
Compressive Phase Retrieval refers to the problem of recovering an unknown sparse signal, upto a global phase constant, given only a small number of phaseless (or magnitude) measurements. This problem occurs in several areas of science - such as optics, astronomy and X-ray crystallography - where the underlying physics of the problem is such that we ...
