Abstract:

This report describes work done to design and fabricate a holographic lens for pilots 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.
