Wide Angle Distortion Free Holographic Head-Up Display

A new optical design of a 60° x 30° holographic display is demonstrated. The arrangement uses two holograms, a relay lens and a Schmidt plate. The first hologram is used as collimator and combiner and gives complete see trough capability. The second hologram is a field hologram. Ray traces and spot diagrams are shown, which have been obtained with a computer program especially developed for this analysis.
