Features of forming holograms of periodic structures in noncoherent light with a reference diffraction grating

The features of forming holograms of periodic structures in noncoherent light using a reference diffraction grating are considered. A device for realizing such recording of holograms is described, and the possibility of forming holograms of periodic structures with arbitrary adjustment of the bands of the holographic structure in the formed hologram is shown. The dependence of the behavior of the grating vector of a holographic structure in the formed hologram on the value of the rotation of the reference grating, as well as on the ratio of the periods of the reference grating and the periodic structure under study, is established.
