Abstract

Reflection holograms of the volume-phase type fabricated with dichromate gelatin have the advantages of achieving efficiencies very close to 100%, of very low noise, and due to its wavelength selectivity, of a chromatic dispersion which can be acceptable in many applications. During several years, the process for production of these holograms has been investigated with the goal of controlling it and achieving good quality and repeatability. Holo-graphic spherical mirrors with dimensions larger than 32" were used in the "Holographic Pancake Window" optical simulator suitable for the training of pilots. These holograhic spherical mirrors were also built as compound holograms with a "white" spectral response very similar to the conventional mirrors. Prototypes of holographic combiners were fabricated and analyzed. Holographic mirrors with optical configurations analog to plane, spheriical and aspherical mirrors are also manufactured to be used as notch filters which will selectively reflect very narrow spectral frequencies, for example, laser radiation. They offer the advantages of high optical densities with high field of view coverage and high photopic transmission.
