摘要：

We study the mechanisms of forming x-ray moire images arising under the action of one-dimensional rows of local concentrated forces at the output surface of a triple-crystalline triple Laue case interferometer for the cases of their orientation parallel and perpendicular to the vector of diffraction. The presence of constant phase shift of one of the interfering waves in the interferometer's analyzer results in the diminishing of period, contrast, and area of deformation moire fringes. It is shown that the area of efficient interaction of phase and deformation moires depends on both the magnitude of the constant phase shift and the magnitude and character of arrangement of local concentrated forces in rows.
