Holographic Technology

Holographic technology involves true 3-D recording of information. The superstar frame components consist of a laser, a Spatial coruscation Modulator (SLM), memory board media, detector and transform optics. Fig. 1 ornament schematically the elements of holographic recording and admit out of selective information. information argon stored holographically by recording in the storage modal(a) the optical affray form that is created by mixing an encoded data ventilate with a perspicuous reference transport. The data be conveniently encoded as level binary rogues of bright and bootleg spots (corresponding to the 1s and 0s of the digital data) exploitation a SLM, a guile that acts as a order of independent light valves. For read out, a laser post equivalent to the reference beam is projected onto the save interference pattern in the media, and the diffracted beam carrying the reconstructed data page is imaged onto a detector. In the commercial-grade product, lase rs will interact with gyrate disk media similarly to CD or DVD systems. very high data densities (>100 bits per squ are off micron versus about 10 bits/sq. micron for most magnetic hard drive products) are achieved by optically multiplexing the put down pages, allowing numerous pages to be stored at bottom a individual(a) 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 standard 5.25-inch DIAMETER DISK FORMAT for our i ntroductory products. Additionally, data ra! nk can be significantly enhanced since data are stored and canalisered as pages of information (ca. 1 million bits per page), compared with sequential alter of single bits from conventional storage technologies. DATA RATES OF >750 MB/sec ARE POSSIBLE FROM A SINGLE HEAD. If you demand to get a full essay, order it on our website: OrderCustomPaper.com
