Abstract
The present paper is concerned with the investigation of imaging properties of As-S-Se media in application for fabrication of holographic optical security elements. Structural changes in such medica under the influence of external factors (exposure or annealing) were studied. Photo- and thermally induced structural changes were directly confirmed by Raman scattering measurements. Surface relief formation properties were investigated with the help of improved amine based solvents, which provided good surface quality. Various types of holographic security elements (HSE) were fabricated and their properties studied. Fabricated surface relief provided high values of diffraction efficiency. For example, diffraction efficiency of such elements as holographic diffraction gratings consisted up to 60 - 70% in non-polarized light. High quality polymer copies of the initial HSE were obtained.
