“…In a classical double-slit experiment, instead of two slits, two virtual sources, obtained as a result of focusing with compound refractive lenses (CRLs) (Snigirev et al, 2009), can be used. Two virtual point sources obtained as a result of focusing can also be used in a double-slit dynamical diffraction experiment (Kohn & Smirnova, 2021, 2022. The advantage of double-slit dynamical diffraction over the classical double-slit experiment is that the interaction of waves with defects and deformation fields will affect the period and intensity distribution of interference fringes.…”

The theoretical investigation of double-slit asymmetrical dynamical diffraction of X-rays in perfect crystals establishes that Young's interference fringes on the exit surface are formed. The position of the fringes in the cross section of the beam depends on deviation from the Bragg exact orientation and asymmetry angle. An equation for the period of the fringes is presented, according to which the period is polarization sensitive. The period increases with increasing the absolute value of the asymmetry angle. In its turn, the size of the interference region also increases with increasing the absolute value of the asymmetry angle. However, the ratio of interference region size to period, i.e. the number of observed fringes, decreases with increasing the absolute value of the asymmetry angle. The size of the interference region can be of the order of a few tens of mm, which can be used for obtaining Fourier dynamical diffraction holograms of a large size. This type of diffraction can also be used for obtaining double-slit dynamical diffraction contrast of defects and deformations. Due to the phase difference information, in comparison with single-slit diffraction, double-slit diffraction is more sensitive to the existence of objects and deformations in the path of the wave.

“…In addition, the defects and deformations of the crystal, in which the fringes are formed, can be investigated using such a type of interferometer. Kohn & Smirnova (2021, 2022 have suggested and theoretically investigated X-ray dynamical diffraction wavefront division interferometers. In these interferometers two coherent focused points on the surface of a crystal, formed by means of a focusing first crystal or a CRL, are used.…”

The theoretical investigation of double-slit X-ray dynamical diffraction in curved crystals shows that Young's interference fringes are formed. An expression for the period of the fringes has been established which is polarization sensitive. The position of the fringes in the cross section of the beam depends on the deviation from the Bragg exact orientation for a perfect crystal, on the curvature radius and on the thickness of the crystal. This type of diffraction can be used for determination of the curvature radius by measuring the shift of the fringes from the centre of the beam.
