In many physical experiments, detectors are only able to measure the intensity of a signal and hence lose access to the phase. The phase retrieval problem deals with the reconstruction of a signal from magnitude measurements, assuming certain physical constraints are satisfied. In this talk, I will briefly discuss the history of this problem and overview some recent progress on proving rigorous stability bounds in infinite dimensions.
