It wasn't based on plasma, though; it was based on nonlinear optical effects in a cube of specially doped glass. When two laser beams of different wavelengths intersected inside the glass, they caused the dopant atoms to emit light. I got to see it in person, and it was pretty freakin' cool.Dave O.Wed, 23 May 2007 18:02:15 -0000http://www.ohgizmo.com/2006/08/06/japanese-scientists-create-true-3d-display/#comment-17586193D technology labs had this technology working on a small scale 10 years ago. See <a href="http://www.3dtl.com/" rel="nofollow">http://www.3dtl.com/</a><br>It is very hard to take this to the next step towards usefulness (I wish the Japanese luck). The status of the 3D technology labs is not clear from the website.steveWed, 23 Aug 2006 05:32:30 -0000http://www.ohgizmo.com/2006/08/06/japanese-scientists-create-true-3d-display/#comment-1758618I saw a display similar to this a few years ago at QinetiQ part of the UK MoD. Im quite sure in the intervening years theyve got alot further. The only problme is the huge computing power required to create a true 3d array.malMon, 07 Aug 2006 18:10:37 -0000
