The word hologram is derived from the Greek meaning "the whole image." A hologram creates a real three dimensional image by reconstructing the light waves that were reflected from the original scene or object. Holograms are made using lasers as the light source, and in general, recorded on photographic emulsions.
Holography, which was developed in the 1960s, is very much a 21st Century visual medium. The three dimensional holographic images show the remarkable possibilities that can be achieved through this manipulation of light. Only with holographic techniques can the artist display accurate, projected three-dimensional light imagery floating in space in front of the hologram with the same perspective, parallax, form and content as the original scene.
These qualities place holography as an important medium in science and art. Scientists use holographic techniques to perform stress analysis, non-destructive testing, create head up displays and encrypt information. Designers create commercial applications such as point of purchase displays, record labels, credit cards security features and many other products. Artists use the medium to create images that are compelling sculptures in light and philosophers study holography to understand the universe and human consciousness, the Holographic Paradigm.
