IMAGE RECONSTRUCTION IN X-RAY PHASE CONTRAST METHOD WITH CRYSTAL ANALYZER IN LAUE GEOMETRY

摘要

Based on Green's function formalism, the wave theory of the formation of X-ray phase contrast with a crystal analyzer positioned in the Laue diffraction geometry was developed. The inverse problem of object image reconstruction was solved in the geometrical optics approximation. The dependence of the method spatial resolution on the object size, the crystal analyzer thickness, wavelength, and reflection order is discussed.
