Abstract
Two fundamental problems have prevented the Leith-Upatnieks Transmission Hologram (LUTH) from popular public display enjoyed by reflection holograms. 1, A laser light source is needed for illumination, which should not exceed five milliwatts in output for the sake of eye safety; and 2, much space is needed behind the hologram for the reconstruction beam. Herein we discuss methods for creating a LUTH display system which is arbitrarily thin regardless of the size of the hologram and arbitrarily bright without safety problems.
