Halographic TV Will Become a Reality

University of Arizona professor Nasser Peyghambarian says that scientists have made a breakthrough in rewritable and erasable holographic systems, a development that could lead to the creation of three-dimensional (3D) holographic displays. Peyghambarian says the breakthrough came when scientists made the first updateable 3D displays with memory. He says the discovery is a prerequisite for any type of moving holographic technology, but it is not presently suitable for 3D images. The researchers produced displays that can be erased and rewritten in a matter of minutes, but to create TV sets with the technology, the images would need to change several times every second. However, Peyghambarian is optimistic that this will happen. He believes that much of the difficulty in creating a holographic TV has now been overcome. “It took us a while to make that first breakthrough, but as soon as you have the first element of it working the rest often comes more rapidly,” he says. “What we are doing now is trying to make the model better.” Holographic TV could be constructed as a screen on the wall, like flat-panel displays that show 3D images, with all the image-writing lasers behind the wall, or it could be a horizontal panel on a table with the technology underneath the surface.
