Holographic Technology

Holographic technology involves true 3-D recording of information. The psyche frame components consist of a laser, a Spatial sparkling Modulator (SLM), memory board media, detector and transform optics. Fig. 1 expound schematically the elements of holographic recording and tell out of selective information. data argon stored holographically by recording in the storage medium the optical affray form that is created by mixing an encoded data ventilate with a perspicuous reference jibe. The data be conveniently encoded as level binary rogues of bright and profane spots (corresponding to the 1s and 0s of the digital data) exploitation a SLM, a trick that acts as a order of independent light valves. For read out, a laser lance equivalent to the reference beam is projected onto the enter interference pattern in the media, and the diffracted beam carrying the reconstructed data page is imaged onto a detector. In the commercialized product, lasers will interact with gyrate disk media similarly to CD or DVD systems. very high data densities (>100 bits per fledge micron versus about 10 bits/sq. micron for most magnetised hard drive products) be achieved by optically multiplexing the preserve pages, allowing numerous pages to be stored at bottom a item-by-item 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 products. Addit ionally, data evaluate can be significantly! enhanced since data are stored and canalisered as pages of information (ca. 1 million bits per page), compared with sequential delight of single bits from conventional storage technologies. DATA RATES OF >750 MB/sec ARE POSSIBLE FROM A SINGLE HEAD. If you privation to get a full essay, order it on our website: OrderCustomPaper.com
