Description: A head-up display greatly improves situational awareness and increases safety by allowing the pilot to see outside while providing all the information necessary to maneuver the aircraft. A head-up display enhances safety by providing the pilot with conformal attitude and flight guidance information overlaid on the actual out-the-window view for precision flying and landing. The objective of this project is to investigate the feasibility of designing a holographic head-up display that can use the windshield as an optical waveguide. The primary focus of the project is to investigate the effect of windshield curvature on the final image displayed to the pilot. The system design was demonstrated by using a projector system that traps light into the windshield waveguide through an injection hologram. The light must internally reflect totally until it reaches the proper height. The light is then directed into the pilot’s eyes through an extraction hologram.
