Abstract
We discuss different holographic materials for thick holograms recording. For material selection we apply various holographic and technological factors. Chalcogenide glasses have good optical properties, low scattering and high resolution for IR application. Dichromated gelatic film and thick layer-gel of dichromated gelatin may be used in visible green-blue light, but these holograms are unstable. Photo polymer PMMA - for hologram recording in visible light we used as base material, which has high holographic quality and good stability. We discuss the synthesis of material and describe the method of latent image for selection of optimal composition and additives. We use the molding method for production of high quality surfaces. A special recording scheme allows the material to record large size elements with highly reproducible parameters. It is shown that in order to obtain highly uniform elements it is necessary to maintain the very strict control of synthesis process. Application of this technology is discussed.
