SIMPLIFIED CONDITIONS AND CONFIGURATIONS FOR PHASE-CONTRAST IMAGING WITH HARD X-RAYS

摘要

A method of obtaining an image of a boundary of an object, the boundaryrepresenting a refractive index variation, the methodincluding irradiating the boundary with penetrating radiation having highlateral spatial coherence and a propagation component transverseto the refraction index variation, and receiving at least a portion of theradiation on an image plane so as to form the image, the radiationhaving been refracted by the boundary such that the boundary is represented onthe image by a corresponding intensity variation.
