description: The given work is devoted to experimental detection of surface thin holographic structures - gratings, the study of their properties by theoretical and experimental methods, the formation of relief by irradiation of a photoemulsion with short-wave UV radiation. The existence of a surface grating has been established and some of its properties, such as spatial frequency, diffraction efficiency (DE) and angular selectivity, have been studied. It was found that at high frequencies the DE of the phase hologram is very weak, but a decrease in the spatial frequency by 30% causes an increase in DE by 10.6 times. The proposed, calculated and manufactured holographic setup showed its full operability and made it possible to make rather subtle measurements of the diffraction characteristics of the holographic structures obtained on it. The results of the research have shown a way to increase the diffraction strength of the surface structure recorded in a counter-directional scheme is to lower the spatial frequency of the grating to values of several hundred lines/mm.
