Abstract:Propagation-based phase contrast imaging with a laboratory x-ray source is a valuable
tool for studying samples that show only low absorption contrast,
either because of low density, elemental composition, or small feature
size. If a propagation distance between sample and detector is
introduced and the illumination is sufficiently coherent, the phase
shift in the sample will cause additional contrast around interfaces,
known as edge enhancement fringes. The strength of this effec… Show more
