Here is a picture of how the projection works.

Cant click the link now but isnt this old as fuck? Like at least a year or two. Id say unlikely for a holodeck experience, but give it a few decades and we might see some practical uses in telecommunication

>>7809063
Not a chance. It uses big dangerous lasers that can blind you and literally generate air pollution.

We can fix that with money. Lots and lots of money.

The article is from August 18th, 2015. The study could have been from an earlier date, but desu you sound pretty retarded to me.

man I saw this like a year ago. it's quite a shit hologram technique

Their perception of time is warped, honey.

Are you talking about this?

That's Burton Aerial which was announced in 2011 iirc and it's literally obsolete. This Fairy Lights was announced half a year ago, uses femtosecond lasers and can generate high resolution pictures in a volume of 5 cm^3, the principle is the same but the laser used is more safe (this kind of laser is the same used for eye surgeries by the way).

The main difference between Burton Aerial and Fairy Lights is that the latter was designed to be safer and with physical interaction as focus point, the laser pulse is weaker and much shorter (10^15 pulses per second), that's why the guy in the video is able to touch it with his bare finger.

Nope. If you're gonna heat air to plasma you need a powerful laser. Heating up air to plasma is gonna form NOx, ozone, and other nasty things no matter what.

>>7810915
So how do you get a color other than blue?

>>7810926
Is ozone that dangerous to begin with? the ozonosphere is thinning, I doubt a little ozone generated by these things will unbalance the atmosphere.

>>7810915
Maybe with liquids, projecting the lasers inside a translucent container filled with some chemical or something like that, in the video they show that the laser can generate green and read when projected through a certain glass (refraction I guess), though I didn't read the details yet.

Yes NOx and ozone are very bad for you. NOx reacts with water to form nitric acid in your lungs

>Maybe with liquids
That's not a holodeck then
