Abstract
Holographic optical elements (HOEs) are produced in a variety of materials for a wide range of applications. An ideal holographic recording medium for holographic notch filters would be capable of high index modulation, produce high optical densities, exhibit low scatter, haze, and absorption, and be able to survive harsh environments. None of the currently available recording media possess all of the above characteristics; thus the material selected must suit the application requirements. This paper discusses experimental results regarding the holographic and optical properties of two holographic recording materials: dichromated gelatin (DCG), and Du Pont HRF-700 photopolymer. The strengths and limitations of the two materials, as applied to notch filters, are discussed, and data are presented showing the fundamental characteristics of each.
