Phys. Rev. Lett. 91, 203902 (2003) [4 pages]Unique Phase Recovery for Nonperiodic ObjectsReceived 2 April 2003; published 13 November 2003 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 Letter 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. © 2003 The American Physical Society URL:
