Make Hologram in 60 seconds
12 02 2008Very soon holograms will be made in less than a minute. University of Arizona optical scientists have broken a technological barrier by making three-dimensional holographic displays that can be erased and rewritten in a matter of minutes. The work, which started about two years ago, was done in collaboration with Nitto Denko Technical Corp. and was funded by the U.S. Air Force Office of Scientific Research.
The holographic displays - which are viewed without special eyewear - are the first updatable three-dimensional displays with memory ever to be developed, making them ideal tools for medical, industrial and military applications that require “situational awareness.”
According to the sources the technology will be helpful in medical science. “Three-dimensional imaging techniques are already commonly used in medicine, for example, in MRI (magnetic resonance imaging) or CT scan (computerized tomography) techniques,” Tay said. “However, the huge amount of data that is created in three dimensions is still being displayed on two-dimensional devices, either on a computer screen or on a piece of paper. A great amount of data is lost by displaying it this way. So I think when we develop larger, full-color 3-D holograms, every hospital in the world will want one.”
