"Dots" of plasma created by lasers create a three dimensional figure in open air - Courtesy AIST
By creating plasma in open air with lasers, Japanese scientists are working on a true 3D display

The Japanese National Institute of Advanced Industrial Science and Technology (AIST) announced an exciting breakthrough in optoelectronics -- a working three dimensional display.  The display does not rely on any sort of optical illusion or disorientation. Instead, infrared lasers are aligned to converge and create small amounts of plasma.  The plasma acts as a floating "dot" on top of the laser grid. 

The infrared laser pulses across several reflectors so that 100 dots can be created per second.  The initial reports from AIST are a little light on details, but it appears as though the plasma dots can be drawn up to several meters away from the laser source. It also appears as though the device needs a vapor source with specific electron/ion content in order to generate the dots.

What do you mean "Other things besides dots"?!

That's all digital images are! DOTS! Millions and millions of beautiful glowing dots. I can't wait until they perfect the tech and ramp the dpi^3 :) I'd hoot up my atari 2600 and play space invaders in 3d. That would roxor.

Oh, and a link would be nice

Yeah, and might as well correct that typo :

"The infrared laser pluses across several reflectors "

"The infrared laser pluses across several reflectors "

Ummm, say what? It's pulses, plural of pulse, unless you have some weird sense of humour.

The typo as been corrected, as if you read carefully, I reported the word spelled as "pluses", not "pulses".

You made a type too :)

The google translation on that is horrible. I had to have my girlfriend translate it :(

I know that all digital images are compose of DOTS....I guess talking about the size of thoses dots is more what I meant. Unless you want to play pong 3d ( which could be fun ) with DOTS of that side we're still far from "StarTrek HoloDeck".

dots of that SIZE, not side. An Edit fonction would really be nice.

Or you could just reread your post before pressing the post comment button, ha ha! But I agree that we are far off from any sort of holodeck style images, but all of these baby steps are rather encouraging.

Well... if you remember what was the display device used by computers some 60 years ago, those dots seem to be a pretty good first step.
