That is not how a CRT works. I say whatever you are smoking, you pass it to everyone else.

i think he means that when you hit the CRT screen with a laser, it converts electrons to photons. he's not exactly right, but not exactly wrong either.

But its a cathode ray not a laser right?

There is absolutely no laser in a cathode ray tube. The cathode ray in a CRT monitor for instance is a beam of electrons that is being aimed using electrical and magnetic fields.

OK then, I am not crazy

Very interesting...the pictures show individuals putting their hands through the images and they don't seem to appear to get distorted...I'm totally blank about theories as to how they did it...We're movin into the future. Perhaps it has something to do with their company's name, IO2... Iodine and Oxygen hmmmm...

neither one of you are right...

I combined the ideas of a laser and crt

crt is a vaccum tube that shoots electrons acrosss to phoshphorus coated plate which will make it glow

theres couple ways of making a laser (couple different materials to excite that is), but the basic idea is to excite the material which will alter release a big amount of photons (energy) as the electrons return to their non-excited orbits


Therefore if you find some way of getting any molecule that makes up air into an excited state and then make it release energy, it should create light.

would heavily Ionized air produce this effect?

IO2 ... ionized oxygen?

Pleasma does glow...but I've never seen plasme in free air...

I wonder exactly what the machine does to the air to get that effect.

i am guessing that a matrix of very fine wires are blown up from the base, and the image is projected onto them from below.

By the sound of the video, it seems like this machine is pretty loud. It sounds like it is blowing air or something.

you're right, i don't know what i was thinking. i knew that... really i did!

 

[Czesia]

That's awesome... science fiction becoming reality (again).
Wow.

 

[DanTMWTMP]

regardless....that's still friggin coooool!

i want to see this in like a university lecture, or even just a classroom...just imagine...

 

[m2kewl]

that is cool!

soon there will not be crt/lcd. imagine 3d hdtv in our future :Q

Dude its just a prototype.

I remember reading about a 3-D display a few years ago. Basically the way it worked was this. An image was projected horizontally onto vertically aligned helix. The helix was like a spiral ramp, or better yet, one of those spiral wind socks. Anyways, the helix was rotated at a high rate so that you couldn't see the helix, but you could see the image that was projected onto it, sychronized so that things in the foreground background hit the front or back part of the helix.

So basically its a violent finger cutting projector

I don't think so. Becuase in one of the demos the guy swipes his hand through and blows at the image. It looks like a fine mist is emmited from the machine. So it has to do somthing to the air.

yeah this one is different

This one looks liek it might have a matrix of micro fibers or something blown up into the space above the unit.

Son of a B****.

I have been working on this project for myself for awhile. Im sure my way of getting the image is different, hopefully different enough to get a patent. Ive been working on it for over a year.

NO! I will not elaborate.
