3D Animations In Mid-Air Using Plasma Balls

Posted by kdawson on from the what's-that-crackling-sound dept.

An anonymous reader clues us to research at Japan's National Institute of Advanced Industrial Science and Technology that has produced the ability to make animations by creating small plasma balls in mid-air. The technology doesn't use vapor or strange gases, just lasers to heat up oxygen and nitrogen molecules above the device: up to 1,000 brilliant dots per second, which makes smooth motion possible. When the tech improves it could be used for street signs or advertising.

    It uses high power lasers to heat the air into a "plasma" when running it has the sounds of crackles as mini explosions occur.

    Oh yeah, that's a display I want. Instead of the cat blocking the screen, the cat bursts into flames. How the heck am I going to explain that one to the wife?

    That's why I'm working on my Laser Retinal Projector (patent pending) which aims the lasers directly at the retina. Since the eye is sealed system, there's virtually no danger of toxic gases! What's more, it offers a high degree of privacy, and if you're forgetful it can literally etch the images into your mind for life.*
