One of the most memorable scenes in all of science fiction films is the scene in the original Star Wars movie where Luke first sees the holographic projection of Princess Leia while trying to clean R2-D2. Many fans of that film have been waiting for decades for a similar projection system to launch. Physicists have now created a very close approximation to that Star Wars projection using a laser and particle system. The technique is known as a volumetric display and can make 3D moving images that a viewer can see from any angle. "This is doing something that a hologram can never do — giving you an all-round view, a Princess Leia-style display — because it’s not a hologram,"... Read more...
Microsoft hopes to soon rival the holograms featured in sci-fi works like Star Trek and Star Wars. The company just unveiled compact holographic AR wide-angle displays that it anticipates will advance HoloLens technology. Microsoft has been experimenting with true, phase-only holograms that are created through the interference of laser light. Holograms are often noisy, monochromatic images with low resolution and contrast. Microsoft also remarked that digital holograms often require time-consuming, offline calculations. Its latest technology addresses both image quality and computation speed. Microsoft even contends that its latest real-time holograms can be generated at rates of 90-260 Hz with... Read more...
