Abstract:

This is the final report on a variety of studies of hologram techniques. A summary of the work during the past six years is presented. Reported second are investigations of three areas of holography applications three-dimensional light-line sights for aircraft heads-up displays three-dimensional displays for air traffic control and holographic information storage and display for aircraft. The feasibility of these applications was investigated, and preliminary experiments were performed. Third is the investigation of magnesium bismuth for its usefulness as an erasable recording material. The results indicate that exposures must be controlled very precisely to retain the erasability of the material. Fourth, the summaries of several research efforts are presented. These efforts include an investigation of the information content of three-dimensional images, a study of three-dimensional projection systems, and a study of the properties and aberrations of holograms. Finally, a list of all publications, reprints of publications, and a list of inventions, all produced during the last two years, are included in the appendices. These publications describe the additional work performed under this contract in the areas of temporally modulated holography, the characteristics of high-efficiency dielectric holograms, desensitized hologram interferometry, and other such topics.
