Abstract

The possibility of reconstructing the internal structure of one-dimensional phase objects at diffraction focusing of X-ray spherical wave was investigated. As a crystal analyzer a strongly absorbing wedge-shaped short period superlattice with a rib parallel to the diffraction vector was used in symmetric Laue geometry case. It is shown that by moving a phase object along the direction of diffraction vector one can bring different satellites in the focusing condition. It is possible to restore an additional wave phase acquired in the phase object by recording the entire map of obtained data.
