摘   要: The classic phase retrieval problem refers to the reconstruction of a
function from the magnitude of its Fourier transform. It amounts to reconstructing
the phase information of the Fourier transform from magnitude only, and hence the
term "phase retrieval". Phase retrieval has seen growing applications in signal
processing and particularly in many imaging problems. Today phase retrieval problem
has been extended to the more general problem of reconstructing a
function (an image or a signal) from the magnitude of some transform of it.

Substantial progress on phase retrieval has been made in recent years both in
theory and applications. Nevertheless there remains numerous open problems, many
appears to be extremely challenging. In this talk, I'll give an overview of the
phase retrieval problem and present some of the latest advances as well as
open problems in the area.
