X-Ray Phase Contrast in a Superlattice in the Presence of a Temperature Gradient
In problems of X-ray phase contrast in dynamic diffraction of a spherical wave, it is recommended to use a highly absorbing superlattice plate with a small period in the Laue geometry as an analyzer crystal. By choosing the value of the temperature gradient, it is proposed to focus all the satellites on the exit surface of the sample, guided by the lens formula for a crystalline medium. A method for recording reflexes without additional movement of the phase object is described.
