“…We show how such a setup can be used to provide better control over results that were previously obtained by chance [7]. The preservation of spatial lattice coherence between such crystal slabs has been demonstrated previously in both X-ray and neutron interferometry [8][9][10].…”

“…Unfortunately, the experiments that were carried out using the three-crystal interferometer were not successful, primarily because the relatively small distance between the crystals made it impossible to use the standard microscope apertures to extract a ray path corresponding to the Mach-Zehnder setup. In X-ray [8,9] or neutron [10] interferometry, the functioning of a Mach-Zehnder setup can be confirmed by inserting a variable phase shifter into one of the arms of the interferometer. Its absence in our experiment makes the results difficult to interpret.…”

Recent advances in transmission electron microscopy and specimen preparation now permit the revival of an old idea, originally pioneered by Marton, of using single crystals as amplitude division beam splitters. As a first step in the direction of realizing a three crystal electron interferometer, we present results obtained from a double crystal interferometer, in which the gap between the two crystals is under experimental control and perfect registry is obtained by using focused ion beam milling to fabricate the interferometer from a single Si crystal.

Numerous advances have been made in X-ray technology in recent years. X-ray imaging plays an important role in the nondestructive exploration of the internal structures of objects. However, the contrast of X-ray absorption images remains low, especially for materials with low atomic numbers, such as biological samples. X-ray phase-contrast images have an intrinsically higher contrast than absorption images. In this review, the principles, milestones, and recent progress of X-ray phase-contrast imaging methods are demonstrated. In addition, prospective applications are presented.

“…The complex amplitudes in the detector plane were determined by the method of interference fringe scanning quite often used in X-ray interferometry [68,69]. For the interference fringe spacing Dr % 2X6 mm (Dr laDy), it was possible to obtain the images of phase objects about 6 mm in size.…”

Different X-ray holography methods are reviewed and their features and capabilities discussed. Particular attention is paid to the fluorescence holography method, which allows obtaining three-dimensional local structure images of ordered objects with atomic resolution. Using concrete examples, it is proved that X-ray holography is a unique nondestructive structural characterization method for a wide class of objects.Physics ± Uspekhi 58 (4) 365 ± 383 (2015) #2015 Uspekhi Fizicheskikh Nauk, Russian Academy of Sciences Contents 1.
