Now this is something that really seems sci-fi. Projecting an image into mid air that is visible from any direction.
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.
How soon till we get this:
