Investigations of a Goggle Design Utilizing Holographic Optics.
Abstract
This report covers a preliminary design effort to develop a one-tube, two-eye goggle utilizing holographic optical elements. The major objective of this effort was to determine the feasibility of using holographic optics in a goggle system with its requirements of wide field-of-view, high efficiency, and good image quality. Because of the dispersive nature of holograms, holographic lenses operate best over a narrow band of wavelengths; for the night glass application, therefore, holographic elements were considered only for the portion of the optical train following the image intensifier. In the course of this design effort, nine variations of a basic system configuration were evaluated in terms of imaging criteria, aberrations, and efficiency. Two designs showed promise, although further improvements are necessary. One design is all-holographic and offers a minimum of complexity, but appears to require new techniques to achieve the required performance levels. The second promising design included two hologram lenses and two conventional lenses (for each eye) but was more complex than the all-holographic system. (Author)
