The case of a diffraction image of screw dislocations arranged parallel to the surface of a specimen was studied experimentally and by methods of computer simulation. Special features of scattering of an X-ray wave field in a strongly distorted region near the dislocation core were considered. It was shown that the diffraction image in the vicinity of the defect was formed due to a superposition of new wave fields generated at each point of the elastic field around a dislocation with the existing fields.
