Abstract
A system and method are disclosed for producing and displaying a one-step, edge-lit hologram. For production, an object beam and an edge-lit reference beam are directed at holographic recording material and to interfere with one another. The holographic recording material and the object beam and edge-lit reference beam are then translated with respect to one another. The translation successively exposes multiple portions of the holographic recording material to the interference of the object beam and the edge-lit reference beam to record an edge-lit hologram on the holographic recording material. In one embodiment, the holographic recording material is moved while the object beam and the edge-lit reference beam remain generally stationary. In another embodiment, the object beam and the edge-lit reference beam move in unison with each other while the holographic recording material remains generally stationary. A base enclosure is preferably formed to removably receive an edge of a plinth having an edge-lit hologram mounted thereon. A light source may be positioned within the base enclosure to provide an illumination beam to reconstruct the edge-lit hologram when the plinth is receiv…
