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.
