Abstract
A holographic storage system and method are provided in which a light source (12) is used to generate a coherent light beam which is split into a reference beam (18) and an object beam (20). The reference beam (18) is directed to the holographic storage medium (22) through use of a reference beam multiplexer (24). The object beam is encoded with a pattern encoder (34) and directed to the holographic storage medium (26). During read out, the object beam is reconstructed and detected by an optical detector (40).
