Paper Abstract

It is well-known that the loss of phase information at detection means that a diffraction pattern may be consistent with a multitude of physically different structures. This paper shows that it is possible to perform unique structural determination in the absence of a-priori information using x-ray fields with phase curvature. We argue that significant phase curvature is already available using modern x-ray optics and we demonstrate an algorithm that allows the phase to be recovered uniquely and reliably.
