Abstract

Phase retrieval implies extraction of the phase of a complex signal from its modulus. In the context of wavefront sensing, the unknown wavefront is represented as a phase across an aperture and the observable is the modulus of the diffracted light, measured in a convenient image plane. In this paper we give a concise statement of the problem, review some proposed solutions, discuss the question of uniqueness, give elementary examples of phase retrieval, and show how the concept might be used in an imaging context.
