Local deformation in diamond crystals defined by the Fourier transformations of Kikuchi patterns

A new approach has been proposed to determination of local strains in crystals using patterns of electrons backscattering diffraction (Kikuchi patterns) and discrete two-dimensional Fourier transformations. The new approach has been tested in studying diamond samples synthesized under different conditions. The results obtained have been found to agree well with the data obtained by other methods.
