The study, analysis and computer simulating of the diffraction contrast of crystal structure defects are carried out in the laboratory. The new X-ray optical diffraction effects (diffraction focusing of X-ray Bloch waves on perfect crystals; dynamic diffraction focusing on bent crystals; guide wave effect and channeling effect, X-ray interferometry in continuous spectral radiation) have been detected and investigated. The investigations of short-wave radiation scattering in the short-range diffraction field are carried out. The schemes of focusing X-ray optical elements are proposed. Diffraction peculiarities in disordered quasicrystals are investigated. The software package was worked out to interpret and simulate diffraction images obtained by Laue, Debye, pendulum and widely divergent beam methods [21-26].
