Chicago: , reports Reuters.
This technology will take researchers a step closer to 3-D real-time images, an advance in holographic technology that could make video conferencing far more lifelike. The technology branded as three-dimensional telepresence will address shortcomings of current holograms, which give the illusion of 3-D but leave out the rear view, said Peyghambarian, whose study appears in the journal Nature.
Researchers foresee the application of the current technology in many areas like car or plane manufacturing where the designers can look at the hologram and design the system they have in real-time and look at the model and make changes on it as they go. It will also allow surgeons world wide to participate in real time operations. They also believe that earlier adoption of the technology will happen in movies where 3-D is already gaining popularity.
To generate the hologram, cameras obtain color images at various angles and send them over an Ethernet line. In the lab model, images are projected onto a transparent plastic panel and refreshed every few seconds. Potential displays will lie flat on a table and the system will create an optical chimera that the image is floating above the screen. With the hologram, no special glasses are needed and the number of perspectives is only limited by the number of cameras used. With the hologram, no particular glasses are needed and the number of perspectives is only restricted by the number of cameras used.
"This breakthrough opens new opportunities for optics as a means to transport images in real time," Lynn Preston, director of the National Science Foundation's Engineering Research Centers program was quoted by Reuters. However, it will be far longer before the system can be used by ordinary consumers.
