Holographic Data Cards

Magnetic strip data cards have revolutionized commerce, but they are vulnerable to erasure by exposure to magnetic fields and there are pretty significant constraints on how much data they can contain. In contrast, Holographic Data (HD) Cards are not vulnerable to such erasure and can store orders of magnitude more data through holographic data storage technology. A holotechnology memory device that can store as much as five gigabytes could replace flash memory for many usages. It would be a boon to handheld machines especially smart phones and PDAs. Next generation smart phones may use holotechnology science for both memory and display functions. For memory, holotechnology information storage and retrieval can greatly increase the storage capacity of phones. For display, holotechnology projection can show pictures, unconstrained by the tiny size of a handheld device. The prospect of watching television on a mobile phone is a hot idea now, but who really wants to see TV on a 2" screen? If it were possible to project a large picture from a cellphone onto the wall nearby, that would transform the use of cellphones for visual media. The page on how holographic data storage works discusses further information and sources.

Holotech information storage and processing transcends the "surface barrier" because different pages of information are recorded and retrieved in three dimensions in overlaid slices permeating the depth of storage media. Large numbers of holographic pages can be recorded in a holographic cube (holocube). Alternative page are stored and accessed using reference rays with different incidence angles or wave phases. Data storage density for three-dimensional holotechnology systems may be orders of magnitude greater than that of two- dimensional optical or magnetic systems.

There are numerous potential uses of holographic information systems in the general area of interactions and imaging. "HoloCams" will employ holotechnology information recording and playback to store and project 3D perceptual environments. Holographic computer graphic interfaces and interfaces, including gesture interpretation systems, will support much more natural interaction between humans and computers than can be done with current two- dimensional displays and keyboard with mouse. Holographic imaging with temporal gated pulses will support high-resolution views of things surrounded by light refracting matter such as body fluid or translucent atmospheres. See medichips as well for more about holotechnology.

In the practice of medicine, holotechnology imaging and tomography will probably become key to computer-assisted diagnostic purposes and treatment. The capacity of gated holography to produce sharp pictures of things within translucent fluid may make it the imaging modality of choice for multiple biomedical applications. Similarly, medical researchers are developing usages of holotechnology applied science for the formation of 3D computer models of patients' anatomical structures and features. Such holotechnology models are then used to fabricate customized implants and prostheses. holographic technology and biomedical design also is of interest.
