Dynamical diffraction model for phase-contrast analyzer-based imaging

Abstract Authors suggest a theoretical model of X-ray phase-contrast analyzer-based imaging for non-crystalline objects of an arbitrary shape. The complete multiplicity of X-ray scattering has been taken into account in both the monochromator and analyzer crystals, as well as in the non-crystalline sample. The model analytically establishes interrelations between the properties of the object (shape, size, refraction and absorption coefficients) and the experimentally observed parameters of the distribution of the intensity.
