Star Wars-esque 3D holograms--touch hologram in daylight

[jos]

A lot of work is currently going into creating Star Wars-esque 3D holograms that can be seen by the naked eye without wearing 3D glasses, and now researchers have found a way to make safe, touchable mid-air displays using femtosecond lasers.

 

It is possible to create holograms in mid-air using a laser-induced plasma display, which works by ionising air molecules so that they release extra energy in the form of bluish-white photons that can be seen easily.

 

The plasma photons are known as 3D pixels, or rather voxels, and at the moment, the lasers used to make 3D holograms are nanosecond lasers, meaning they fire tens or hundreds of thousands of times per second to heat up specific points of air.

 

It is not safe to come into contact with such a holographic display, as ionised air molecules will definitely burn human skin.

 

Instead, Japanese researchers from 3D display firm Aerial Burton and four Japanese universities have found a way to speed up their lasers so that holograms are safe to touch by using femtosecond 1Kh infrared pulsing lasers, which fire every millisecond.

 

By using femtosecond lasers, the hologram is safe to touch, and you can feel it.

Imagine all the dicks floating in the air...

[Mo5]

Go Japan!

[Trik'Stari]

........so that's just about the most awesome news this week.

[zanduh]

Well that's amazing. How expensive is it to make though

[deviant88]

Future looks fun..

[Beskamir]

If this is real, which I hope it is, then this is probably the coolest technology that is currently in development. I'd even consider it cooler than VR.

[Yog]

Finally, a hologram technology that isn't literally smoke and mirrors.

[ADM-Ntek]

that is nice and all but i want star trek style holograms. 

[Albatross]

Oh yea, we're getting closer to sharing some of the goods from the Star Wars franchise. :wub:

 

Next we gotta get the real version of the Lightsaber!

[SurvivorNVL]

Star Wars, Star Trek.  Man, this stuff is becoming reality.  Now all we need is a Death Star with a giant American flag on it.  "FREEDOM!"

[PortentousLad]

It's going to be weaponised before we can warn Luke about impending doom.

[Sors]

No F****** Way!

[Doobeedoo]

I can touch Miku ?

[WereCat]

I am actualy surprised how this didnt get much atention as it is freaking awesome!

I wonder when we will see this in stores ... not soon for sure

[Trik'Stari]

I wonder, how long before we get to this point

Won't be long I imagine.

[CTR640]

I wonder, how long before we get to this point

Won't be long I imagine.

Lol, I knew someone would come up with a sick joke of touching anime's pussies and I can't blame them though

[cesrai]

Like they said this will be great for emergency and such.

[Embattled]

At this point I don't even care if it's practical, I just freaking want this in my life NOW.

 

Now I could see this be widely adopted if they found some way to miniaturize it and put it in smartphones

[FruitBasketSilex]

Imagine all the dicks floating in the air...

Hologram dicks was my first thought too.

[thexzenon]

This is the best thing that I saw all week  

[werto165]

Wouldn't ionising air be ridiculously loud?
