Abstract
Phase retrieval implies extraction of the unknown phase of a complex signal from modulus data. It has been proposed for use in a variety of applications, including wavefront sensing, electron microscopy, signal design, and reconstruction of atmospherically degraded images. Solutions to the problem involve measuring the modulus in one or two conjugate domains; using an apodized aperture; using several, slightly defocused images; and forming an estimate of the signal's power spectrum based on multiple, degraded measurements. In this review paper we define the problem, show how phase retrieval can be used in some of the areas mentioned above, outline various solutions that have been proposed, give several examples, and present a fairly extensive bibliography on the subject.
