Abstract
Gabor phase retrieval refers to recovering a square-integrable function from the absolute values of its Gabor transform (short-time Fourier transform with a Gaussian window), up to a constant factor. The talk studies Gabor phase retrieval based on discrete sampling points, considering three types of sampling sequences corresponding to square-root lattices, square-root sequences on two intersecting lines, and square-root sequences on three parallel lines, with optimal sampling densities derived for each case.
