Abstract: The review describes the operating principles and capabilities of X-ray refraction introscopy, which involves the use of a crystal analyzer as an angular filter. Methods for obtaining absorption, refraction, and extinction contrast, and various image processing algorithms to implement two-dimensional and three-dimensional visualization are considered. Also given are examples of applying the method in biomedicine and materials science.

Keywords: X-rays, refraction, diffraction, small-angle scattering, introscopy, crystal analyzers, visualization.
