We study the problem of phase retrieval from a deterministic viewpoint, in which the magnitudes of a time-frequency or time-scale representation of a signal are known. From an inverse problems perspective, the questions of uniqueness and stability are crucial to theoretically guarantee meaningful reconstruction. In this talk, we present results on these two questions for Gabor frames and wavelet frames and conclude by discussing some open problems.
