HOLOGRAPHIC HEAD-UP DISPLAY, PHASE I
Abstract
A head-up display system as used by an aircraft commander must provide a simulation of the real-world exterior to his vehicle, and, at the same time, represent any change in his attitude with respect to a predetermined segment of this real world. In the particular case of an aircraft landing approach, one can characterize the pilot's view of the aircraft carrier and its subsequent variations into six degrees of freedom. The display must provide the view corresponding to the instantaneous values of these parameters and change as any one or more of the parameters change. This report describes the development work on displays of this type using side-band or carrier-frequency Fresnel holographic recorded images. An important feature of the holographic approach is that a true 3-D image of an object can be recorded. It is, therefore, possible with a single hologram to present an infinite number of different views of an object to an observer. Continuous control of the pertinent parameters is required to make a dynamic real-time display. High quality holograms of aircraft carrier models have been made in sizes up to 8 by 10 inches. Techniques and systems for manipulating the holographic real and virtual images from these holograms have been tested and are described.
