Review of Random Phase Encoding in Volume Holographic Storage
Random phase encoding is a unique technique for volume hologram which can be applied to various applications such as holographic multiplexing storage, image encryption, and optical sensing. In this review article, we first review and discuss diffraction selectivity of random phase encoding in volume holograms, which is the most important parameter related to multiplexing capacity of volume holo...
متن کاملOverloaded phase-code multiplexing for volume holographic storage.
Overloaded phase codes for volume holographic data storage are introduced. In contrast to any previous phase-code design, overloaded phase codes enable multiplexing of a number of data pages that exceeds the number of utilized reference beams. In this way the achievable data capacity can be augmented. Overloaded codes are generated by extending multilevel phase codes based on the discrete Fouri...
متن کاملProgress in read–write fast–access volume holographic data storage
We review recent progress made towards commercializable read–write, fast–access holographic data storage. This includes a recent demonstration of high areal density holographic storage [1], systems architectures for extending this high density to high capacity using phase–conjugate readout [2], and recent experimental progress along these lines. Other topics include using signal processing to r...
متن کاملCompensation for pixel misregistration in volume holographic data storage.
We describe what we believe to be a novel postprocessing algorithm for compensating for misregistrations between a detector array and the coherent image of a pixelated two-dimensional data page. A lookup table of baseline local offsets is combined with the dynamically measured global offset of the received data page, producing an estimate of the total lateral shift of each small block of pixels...
