The hardware and software of a stand for measuring the angular selectivity characteristics of transmission and reflection holograms have been upgraded. As a result, the information content and the accuracy of optical signal measurements have been increased. The angular selectivity characteristics of holographic gratings with arbitrary values of parameters recording beams in thick-layer and thin photopolymers have been measured and analyzed. Based on these data, it is possible to reveal new information on the nature and the inhomogeneity of the spatial structure of analyzed holograms. Recommendations for practical application of various holographic photopolymer materials are presented.
