The report describes work on the development of a hologram lens system for a Head-Up Display HUD System having a 25 degrees field of view, a 25-in. eye relief, and a 3-in. high by 5-in. wide exit pupil. The work includes a parametric analysis study, preliminary system design, development of a red- sensitive hologram recording material, and experimental work on a hologram lens element. The parametric analysis study is based on the Hughes continuous hologram lens design approach, applied to displays. Ray tracing, with efficiency calculations, is used to determine and compare focal surfaces, image distortions, aberrations and pupil errors, for several reflection and transmission hologram lenses.
