Quantum‐mechanical model for phase‐contrast imaging of non‐crystalline objects

Abstract

The quantum-mechanical theoretical model for the quantitative description of phase contrast images from non-crystalline objects with arbitrary shapes has been developed. It takes into account multiple scattering effects both in the object (particularly, refraction and phase change) and in the crystals of monochromator and analyzer. Presence of homogeneously and inhomogeneously distributed microdefects and macrodeformations in monochromator-and analyzer-crystals, which influence significantly on the scattering pattern, has been taken into account.

Solving of Direct and Inverse Scattering Problems for Heterogeneous Non-Crystalline Objects in Analyzer-Based Imaging

“…All further calculations are made using the model, suggested in [15][16][17]. The model allows taking into account the effects of dynamical scattering in both the monochromator and the analyzer, as well as in the non-crystalline object.…”

“…This case is thoroughly studied in work [16]. Another parameter of the object is the thickness of each column.…”
