Paper Abstract

Reflection holograms of the volume-phase type fabricated with dichromated gelatin have the advantages of achieving efficiencies very close to 100%, very low noise, and, due to their wavelength selectivity, a chromatic dispersion that can be acceptable in many applications. For several years, the production of these holograms has been investigated with the goal of controlling their processing and achieving high quality and good repeatability. Holographic spherical mirrors with dimensions larger than 82 cm were used in the holographic Pancake Window optical simulator suitable for the training of pilots. These holographic spherical mirrors were also built as compound holograms providing a "white". spectral response very similar to that of conventional mirrors. Pro totypes of holographic combiners were fabricated and analyzed. Holographic mirrors were also manufactured for use as notch filters, which selectively reflect very narrow spectral frequencies, for example, laser radiation. They offer the advantages of high optical densities with large field-of-view coverage and high photopic transmission.
