COMPACT HOLOGRAPHIC STORAGE DEMONSTRATOR WITH RAPID ACCESS

We discuss the design of a complete, compact holographic storage demon strator based on a combination of spatial and angular multiplexing and using acousto-optic deflectors for rapid nonmechanical access. We als o describe the implementation of this design and preliminary results o f both the analog storage and the retrieval of 20,000 holograms in twe nty 1-mm-thick layers of a lithium niobate crystal and of the digital storage and error-free retrieval of color images by using error-correc ting techniques.
