The amplitudes of wave fields inside a macroscopically deformed crystal with defects are obtained in the two‐beam approximation. The amplitudes of coherent (strong Bragg and “quasidiffuse”) and diffuse waves emerging from the crystal are determined by taking account of boundary conditions for both Bragg and Laue cases of diffraction. The general expressions for coherent and diffuse components of the differential reflection power of bent crystals with microdefects are obtained.
