Application of Photopolymer Materials in Holographic Technologies.

The possibility of the application of acrylate compositions and Bayfol HX photopolymers in holographic technologies is considered. The holographic characteristics of materials, their advantages, and limitations in relation to the tasks of obtaining holographic elements based on periodic structures are given. The conditions for obtaining controlled two and multichannel diffraction beam splitters are determined with advantages in terms of the simplicity of the fabrication process.

Holographic formation and diffractive properties of hybrid periodic structures.

The paper presents formation processes and diffraction properties of hybrid periodic structures such as volume gratings with refractive index modulation, on the surface of which relief gratings are formed. It is shown experimentally that relief gratings with significant diffraction properties in used photopolymer materials are formed in a narrow range of exposure parameters. It is established that the formation of a relief grating on the surface of a volume grating leads to significant changes in the selective properties of structures.
