Dispersive coherence-enhanced radiology: Experimental test and modeling

Can the photon energy dependence of coherence-enhanced radiographs lead to elemental identification? Our tests pave the way to a positive response by showing that image details do change as the photon energy crosses an absorption threshold. The observed changes are explained by a simple model of the interplay between the real and imaginary parts of the refractive index. (C) 2002 American Institute of Physics.
