3-D Projection Tech Makes Images Hover in Mid-Air, No Screen Necessary

Using lasers to excite nitrogen and oxygen in the air, the Aerial 3D system produces natural 3-D images in space without using a screen. Tokyo-based Burton company claims it's the first 3-D tech that casts three-dimensional objects in mid-air without using any kind of screen. It recalls that scene in Star Wars where the crustacean-faced guy is planning the rebel battle plan around his big holographic table.

Rather than using a screen to generate the illusion of three dimensions, Aerial 3D is a laser system that uses beams of light projected from below to generate plasma excitation in atoms of oxygen and nitrogen in the air. It currently can create 50,000 points of light per second, giving it a somewhat choppy frame rate of 10-15 fps. Burton is working to improve that to 24-30 fps.
