-Caveat Lector- >From The Independent (Bangladesh,) http://independent-bangladesh.com/news/mar/21/21032001ft.htm#2 The floating 3D hologram Scientists have developed a Star Trek style hologram device that creates three dimensional images which float in the air. Normally, the three dimensional (3D) image is seen 'inside' a hologram display or viewed with special glasses. But in the world of science fiction, holograms are often depicted appearing out of thin air.The idea was used in the films Star Wars and Back To The Future, and on TV for the starship Enterprise's "holodeck" in Star Trek - The Next Generation. Scientists at the Defence Evaluation and Research Agency (Dera), in England, have discovered how to produce real life floating holograms projected from a computer screen. The breakthrough, reported in New Scientist magazine recently, could enable surgeons, designers and architects to manipulate 3D moving images in mid air. Car designers will be able to extend a vehicle's bodywork just by waving a stylus. Surgeons will be able to examine 3D brain images.Working with the Ford Motor Company, Dera plans to have its first products based on advanced computer-generated holography (CGH) on the market in 2003. Chris Slinger, head of holography at Dera, said: "We can create a real image floating in 3D space. Unlike other techniques, such as stereography or virtual reality, CGH doesn't require people to wear cumbersome headgear to see the image, and prolonged use doesn't lead to any ill effects. Users manipulate images using tools that exist partly as real objects and partly as virtual tools. It is like nothing else we have seen before."A hologram is essentially an interference pattern generated from the object being depicted. When light strikes the hologram it is diffracted, forming a series of wavelets.Interference between these wavelets produces wavefronts that simulate the light that would have come from the original object. With the new system, the computer produces interference patterns that simulate the light waves from an object hanging in empty space. As a result, the image can be projected in front of the screen. In the prototype device, a mirror focuses the image so that it can be seen from a range of angles. As well as displaying images of real objects, the system can also project the shapes of imaginary objects. - LPS <A HREF="http://www.ctrl.org/">www.ctrl.org</A> DECLARATION & DISCLAIMER ========== CTRL is a discussion & informational exchange list.
