Abstract
A multiple image multiplexed holographic display including a light pipe (11, 111) having first and second opposing surfaces (11a, 11b, 111a, 111b) and a plurality of input surfaces (15, 115) located between adjacent edges of the first and second opposing surfaces. A multiple image hologram structure (13, 113) attached to one of the first and second opposing surfaces is illuminated with respective beams injected into the light pipe by a plurality of light sources (17, 50, 61) adjacent respective input surfaces. The injected beams are incident on the hologram structure at different incidence angles, and the hologram structure contains holographic images that are recorded to reconstruct in response to respective injected beams, whereby each holographic image is selectively displayed by controlling its associated light source.
