Holographic Technology

Holographic technology involves true 3-D recording of information. The top dog frame components consist of a laser, a Spatial illume Modulator (SLM), memory board media, detector and transform optics. Fig. 1 expatiate schematically the elements of holographic recording and aim out of info. selective information argon stored holographically by recording in the storage culture medium the optical affray form that is created by mixing an encoded data ventilate with a perspicuous reference burn. The data atomic number 18 conveniently encoded as level binary rogues of bright and vestige spots (corresponding to the 1s and 0s of the digital data) exploitation a SLM, a twisting that acts as a order of independent light valves. For read out, a laser glisten equivalent to the reference beam is projected onto the preserve interference pattern in the media, and the diffracted beam carrying the reconstructed data page is imaged onto a detector. In the mercenary product, l asers will interact with gyrate disk media similarly to CD or DVD systems. very high data densities (>100 bits per jog micron versus about 10 bits/sq. micron for most magnetic hard drive products) be achieved by optically multiplexing the record pages, allowing numerous pages to be stored at bottom a undivided small spatial region of the media.

The baron to multiplex recorded pages is derived from use of the thickness (3rd dimension) of the media. Consequently, CAPACITIES OF >100 GB atomic number 18 ACHIEVABLE in half-millimeter thick media IN A banner 5.25-inch DIAMETER DISK FORMAT for our introductory pr oducts. Additionally, data place can be sig! nificantly enhanced since data are stored and canalisered as pages of information (ca. 1 million bits per page), compared with sequential deepen of single bits from conventional storage technologies. DATA RATES OF >750 MB/sec ARE POSSIBLE FROM A SINGLE HEAD. If you mendicancy to get a full essay, order it on our website: OrderCustomPaper.com
