The aim of the work is the development of supplementary methods to test and indentify holograms using atomic-force microskopy and analisis of a diffraction structure in the far field. Developed and aсcepted is the method for mapping HPE surface nanorelief. Investigation of HPE parameters and those of HPE matrixes with the aim to indetify them were carried out.
