Japan’s AIST Develops True 3D Image Projector
The newly developed device, however, creates real 3D images by using laser light, which is focused through a lens at points in space above the device, to create plasma emissions from the nitrogen and oxygen in the air at the point of focus. Because plasma emission continues for a short period of time, the device is able to create 3D images by moving the point of focus.
… At the moment, the distance at which the device can project images is limited to between 2 and 3 meters. Improved laser technology will enable images to be projected at greater distances and with more color, so we may soon see 3D images floating above our city skylines.
I can see uses for the technique, but I am not looking forward to “3D images floating above our city skylines”.
And how is that more annoying and unsafe than blimps telling you to drink at Tropical Isle or wherever?
Does thos mean that someday I’ll be able to play checkers on the Holodeck with Moe Howard?
I don’t like blimps either. Checkers with Moe sounds good.
I kind of liked the ad-blimps in Blade Runner…And if I had a holodeck I’d never get anything done.
