The thin holographic diffraction gratings with periodic surface/internal spatial phase modulation are investigated. The dependences of the efficiency in the various diffraction orders are measured and calculated in supposed profiles of phase relief. The calculated results are compared with experimental data of holographic phase gratings recorded in self-developing photopolymers. The numerical values of the phase shift Df of experimental samples are determined. It was found, that the surface relief conforms satisfactory the two-parabolic model, whereas the internal modulation profile in the volume of photopolymer can be well described with two-cylindrical model of the phase relief.
