Abstract

Size reductions of reflex type sights and head-up displays (HUDs) can be achieved with holographic components. For the reflex type sight, the image formed by a high-quality optical system is recorded in a holographic plate with an edge-illuminated reference beam. This hologram reconstructs the original image and duplicates its original quality. The system is compact, consisting of a hologram on a flat glass plate and a compact laser beam expansion optics. The illuminating beam enters the hologram plate through its edge. The laser is remotely located with light guided through a fiber optics cable to the sight. HUDs can also be made more compact by using a pair of gratings attached to a flat glass plate. The plate guides the display to a position in front of the pilot and occupies a small volume.
