A major focus of this effort was on large aperture 10 inch holographic optics, the application of wavelength shift techniques to the holographic telescope, and infrared optics. One of the more promising results of the study were designs that use holographic optics in the infrared. A two element telescope was designed using wavelength shift techniques where the elements were made in the visible spectrum and reconstructed at 10.6 micrometers. Both transmission and reflection elements were fabricated during this contract. Several other areas were also addressed wide angle reflection holographic optics and the development of facilities for producing high quality elements. Holographic optics have some very attractive features and attributes. Further, the producibility of large aperture elements illustrates another advantage of holographic optics.
