Holographic Technology

Holographic technology has been the subject of research for decades, but is now moving into greater commercialization in a number of products and services. Identifying holograms are providing greater security for a variety of products. Holographic data disks are moving toward commercialization in response to growing needs for high- capacity data archiving. For holographic data encoding, first a laser ray is divided in two. Then one of the resulting rays is passed by means of a Spatial Light Modulator that converts configurations of electronic information into white and black configurations in the laser ray. This ray becomes the "signal" ray. The second ray becomes the "reference" ray. Then the two rays are focused and intersected inside an optically sensitive recordable media. This intersection makes a chemical reaction between the storage media and the configuration of overlapping peaks and troughs of the two beams of light. This burns the information into the media in the form of a hologram. To retrieve the data, a beam with identical wavelength and angle as the original reference beam is focused within the media, the signal beam is retrieved, and the white and black configurations are changed back into electronic information via the use of a Digital Camera Detector (DCD). Three-dimensional holotechnology data storage can store considerably more information in the same size object than can surface-only, data storage systems such as present day CDs and DVDs. There is novel news at the potential for holographic data storage that may also be useful.

In the practice of medicine, holographic imaging and tomography will probably become central to machine-assisted diagnostic purposes and treatment. The capacity of gated holography to produce sharp pictures of elements inside translucent liquid may cause it to be the method of imaging that is preferred for many medical uses. Also, medical researchers are working on applications of holographic applied science for the creation of three-dimensional computer models of patients' organs and external features. These holotechnology models are then used to fabricate customized implants and prostheses. Similar holotech coverage at medical holography may be of interest.

In the fields of teleinteractions and education, teleconferencing and distance instruction science and equipment featuring 2D screen images will evolve into 3D, bidirectional holopresence systems. Holographic applied science is, even now, being applied to "HoloCells" (holotechnology cellular phones that record and play three-dimensional, rapid-response images of the communicating parties that may be viewed from different angles). Linked page holographic human-computer interfaces also deals with these technologies.

When it comes to marketing, holomarketing or "holopromotion" is the use of holographic technology to three-dimensional, high- resolution product promotion. Marketing and purchasing functions can be put togetherd in responsive holograms that both attract consumer interest and make a sale on the spot. Holoactive booths and vending machines that can project consumer-bidirectional pictures many times their size will take up much less space than traditional kiosks and vending machines.
