MessageToEagle.com - Moving holograms have long been considered science fiction, but now with new technology
emerging you will soon be able to see how holograms do almost everything, from watching TV, playing chess, walking
the dog or even talking to you, giving you advice.
Holographic technology is not as new as many people think. The first holograms were invented by Dennis Gabor in 1947.
He was trying to find a method for improving the resolution of electron microscopes.
Unfortunately, Gabor had no access to lasers which are necessary fro creating and displaying good holograms.
Instead, Gabor experimented with a mercury vapor lamp, which produced monochrome blue light, and filters made
his light more coherent.
Gabor won the Nobel Prize in Physics for his invention in 1971.
Ever since Gabor made his first attempts to create holograms, scientists have constantly worked on improving this technology.
Today, thanks to a breakthrough in 3D holographic image technology, it is possible to watch a projection of a three-dimensional moving image without the need for special eyewear such as 3D glasses or other auxiliary devices.
This new holographic telepresence has been developed by optical sciences professor Nasser Peyghambarian and his team at the University of Arizona.
"Holographic telepresence means we can record a three-dimensional image in one location and show it in another location, in real-time, anywhere in the world," said Peyghambarian, who led the research effort.
Holographic telepresence technology can be used in a variety of areas such as telemedicine, advertising, updatable 3D maps, and entertainment.
"Surgeons at different locations around the world can observe in 3D, in real time, and participate in the surgical procedure."
"The system is a major advance over computer-generated holograms, which place high demands on computing power and take too long to be generated to be practical for any real-time applications."
For the time being the telepresence system can present in only one color, but professor Peyghambarian and his colleagues are now working on a multi-color version which will be available in the near future.
