Cool! But the video flickers so much it's kinda hard to watch -- near seizure material. Hopefully that's just a frame rate mismatch between the 3D projector and the video camera, and the image would look much steadier in person.

Pretty awesome... although being that it requires high power lasers to work in air, does that mean that if you happened to look down on the projector that you'd be blinded?

This is the new shit.

Didn't I see this at Epcot center in 1987?

Holy hell, The Future! it's.. arrived

15 fps right now is decent. The crazy flickering very much looks like effects caused by the camera shutter. There are moments where it looks quite stable and smooth while sometimes it looks way off where you can see different fields in the picture that are off by a frame. I like that they should be able to make finer and faster displays with some experimentation and refinement. The use they showed in a larger more lit environment was great since the laser beams weren't as visible while the plasma pixels were still quite bright. Very neat!

I hope so. I'd guess they used a 60Hz cam to record a 24Hz or so hologram; otherwise, this video would be irrelevant.

He talks about digital signage and hospitals, but we all know what it will REALLY be used for:

Porn and videogames.

How is this accomplished? (I don't know how to use google.)

My guess is the focal point of the laser causes the molecules at that point to become plasma which radiates a pinpoint of light, making it a pixel (is a 3d pixel still a pixel?) in the space. Create many pixels in all 3 dimensions, you have a 3d hologram.

The air image is much cleaner (you can't see the lines trailing in/out) because there are far less molecules in the way to bleed off the laser as opposed to water.

Just wait until car dealerships get a hold of this.

I guess its a voxel.

Yeah, I'd say so, voxel is defined as the smallest unit in a 3D space.
