Shift multiplexing with spherical reference waves.
Shift multiplexing is a holographic storage method particularly suitable for the implementation of holographic disks. We characterize the performance of shift-multiplexed memories by using aExpand

Holographic storage using shift multiplexing.
We demonstrate theoretically and experimentally a new multiplexing method for volume holographic storage using a single reference beam that is composed of multiple plane waves or is a spherical wave.Expand

Method for controlling the shift invariance of optical correlators.
Holographic correlators can implement many correlations in parallel. For most systems shift invariance limits the number of correlation templates that can be stored in one correlator. This is becauseExpand

Material transfer recording.
A material transfer technique for image recording is being developed that uses a focused laser beam to transfer ink from a substrate to a recording medium. No other processing is required; theExpand

Holographic memories
Holographic memories can be read-out either with the reference or the signal beam. Reference beam readout reconstructs the stored data whereas signal beam read-out performs a search of the storedExpand

Holographic correlator array with selectable shift invariance
Optical holographic correlators can perform many correlations simultaneously. Because the output plane must be divided among the individual templates in the system, for many systems shift-invarianceExpand
