holographic data storage with polymers

Among the greatest difficulties in the consumer market success of holotechnology technology is the formation of optimal substances and structures for high-volume, rapid-access, safe optically sensitive recordable media. Potential substances include: highly-sensitive photochromic and photochemical polymers; photosensitive crystals such as lithium niobate; organic photopolymers; and glasses. Sony Ups Holographic Storage Speed discusses additional topics.

Holographic science is increasingly used for security uses. Holograms are considerably more tough to counterfeit than patterns (even complex ones) made by standard 2D printing methodologies. For these reasons, holograms are used on recognition cards, bank cards, financial securities, pasathletics, tickets, pharmaceuticals, and important documents and consumer products to decrease counterfeiting. Some countries are already demanding holographic enforcement labels on pharmaceuticals and similar medical- associated products. Most security holograms are currently made by embossing a configuration into an upper "rippled" layer that is adhered to a lower "mirrored" layer. Light bounced off the lower layer and refracted in the upper layer creates the holotechnology image. For more holotech discussion, see Home Virtual Network Videos .
