Coherence-enhanced synchrotron radiology: Refraction versus diffraction mechanisms

Tests performed in different regimes reveal the interplay of two edge-enhancement mechanisms in radiological images taken with coherent synchrotron light. The relative weight of the two mechanisms, related to refraction and to Fresnel edge diffraction, can be changed in a controlled way. This makes it possible to obtain different images of the same object with complementary information. (C) 1999 American Institute of Physics. [S0021-8979(99)03720-2].
