Holographic Lens for Pilot's Head Up Display Phase 4

Abstract

This report describes work done to design and fabricate a holographic lens for pilot's head up display. A holographic head up display (HHUD) trade-off study was done to minimize weight and size of the HHUD. This led to a design for a 25 H x 18 V FOV system with a 3.5 in. (89 mm) circular exit pupil at an eye relief of 26 in. (660 mm). A new design concept was used to reduce the complexity of the relay lens system to a five element asymmetric design. Final system optimization reduced typical errors to 2-5 mrad. Relayless HHUD and holographic relay lens designs were investigated and found to provide moderate FOV and performance, limited by uncorrected hologram aberrations.
