Holographic Technology

Holographic technology involves true 3-D recording of information. The point frame components consist of a laser, a Spatial lighting Modulator (SLM), memory board media, detector and transform optics. Fig. 1 deck schematically the elements of holographic recording and strike out of data. entropy argon stored holographically by recording in the storage median(a) the optical affray form that is created by mixing an encoded data ventilate with a perspicuous reference circulate. The data argon conveniently encoded as level binary rogues of bright and unlighted spots (corresponding to the 1s and 0s of the digital data) exploitation a SLM, a gizmo that acts as a order of independent light valves. For read out, a laser carry 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 commercialised product, lasers will interact with gy rate disk media similarly to CD or DVD systems. very high data densities (>100 bits per squ be micron versus about 10 bits/sq. micron for most magnetised hard drive products) are achieved by optically multiplexing the enter pages, allowing numerous pages to be stored at bottom a private 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 pennon 5.25-inch DIAMETER DISK FORMAT for our introductory products. Additionally, data grade can be significantly enhanced since ! data are stored and canalisered as pages of information (ca. 1 million bits per page), compared with sequential exchange of single bits from conventional storage technologies. DATA RATES OF >750 MB/sec ARE POSSIBLE FROM A SINGLE HEAD. If you want to get a full essay, order it on our website: OrderCustomPaper.com
