Laser puts real 3D-image up in the air!
Japanese scientists have succeeded in the experimental fabrication of a device displaying "real 3D images" which consist of dot arrays in space where there is nothing but air. "Usual" 3D displays draw pseudo-3D images on 2D planes by utilizing
the human binocular disparity. This new japanese device utilizes the plasma emission phenomenon near the focal point of focused laser light.
Maybe this could be the first step to "holographic maps" or "virtual doctors" as seen in Sci-fi movies...
