Within the framework of the generalized dynamical theory of x-ray scattering from imperfect crystals, the dynamical diffuse scattering (DS) by large defects is considered in the case of Laue diffraction geometry. Analytical expressions for DS intensities, which are differential or integrated over the vertical divergence, are obtained for crystals containing homogenously distributed defects, which create around themselves the anisotropic displacement fields of atoms in a matrix. For defects of various types and sizes, the maps of DS intensity distributions in the reciprocal lattice space are plotted, and the influence of the integration over vertical divergence of x-rays on their shape is demonstrated.
