Week2 - Blog # 2 - Holographic
For now, watching TVs and wearing 3D glasses is the ultimate in 3D presentation. However, the rapid development of holography technology is setting the stage for new possibilities and features. Now more than before, the potential of viewing 3D motions in real time is possible. Holography is the process of making holograms using three-dimensional laser techniques. Holograms are 3D graphic images that seem to have depth. Freedman (2002) stated in his article, “A hologram's realism doesn't come merely from its stereoscopic properties; holographic images can be inspected from all angles as the viewer's head moves around them.”
Furthermore, Holographic technology is being used to save and store data. With videos and 3D graphics, gigabytes and terabytes are not enough. This new technology can store way more.
For really large amounts of data, storage capacity is no longer measured in gigabytes, terabytes or petabytes, but rather by the size of the warehouses needed for the discs, cartridges or tapes that carry them. It uses laser beams to store digital data in three dimensions. “Unlike DVDs, which store data in thin layers just beneath the surface of the disc, holographic storage encodes information in three dimensions, within the volume of the disc. This will enable the first holographic discs to store a colossal 300 gigabytes of data--12 times more than the latest Blu-ray discs and 60 times more than a standard DVD” (Economist, 2007).
Moreover, Holographics are being used in many industries, including automobile, airplanes and well as in the military. For example, it has been used in the military to enhance accuracy. An Military & Aerospace Electronics article (2006) describing using new technology by L3 company stated, “The company produces holographic weapon sights for sale to domestic and international military customers, as well as the homeland security and law enforcement markets using advanced laser and holographic technology to enhance optical systems in target acquisition systems” (p. 7).
