Abstract
A holographic display system is disclosed. Utilization of holographic elements provides good transmissivity with respect to both outside stimulus and the superimposed display information. Full color display is enabled by a composite spherical lens and the efficient optical coupling of the display information and the pupil allows the weight of the helmet with the display system to be kept to a minimum.
