Paper Abstract

Modern hard x-ray scanning microscopes generate x-ray beams with lateral sizes well below 100 nm. Characterizing these beams in terms of shape and size by conventional techniques is tedious, requires highly accurate test objects and stages, and yields only incomplete information. Since recently, we use a ptychographic scanning coherent diffraction imaging technique in order to characterize hard x-ray nano beams in x-ray scanning microscopes, obtaining a detailed quantitative picture of the complex wave field in the nano focus and allowing one to reconstruct the exit wave field behind the nano-focusing optic, giving detailed insight into its aberrations.
