Could the technology that MIT’s Michael Bove is working on change computer displays as we know them today? It wasn’t long ago that LCD flat screens took the market over. Are we going to see a similar change when Holographic Video technology matures? A holographic video begins with a computed 3-D model of some moving object or scene. This model “can be thought of as having a whole lot of points on its surface at different depths that change over time,” Bove says. To make that model holographic, a computer needs to figure out the intensity of the light that would be reflected from each point on the object to the point where the viewer’s eyes will be. “You need to create a diffraction pattern that reconstructs all the different intensities for all the different angles,” Bove says. He found that graphics chips in today’s PCs are adept at doing this sort of 3‑D rendering, computing the diffraction patterns, and combining them into a single video output.” |

The upper part is the holographic image??
exactly how much processing power are we talking here?

I think the middle part is some piece of glass like optic stuff. The modulator or something. I suspect this to be the device they have shrunken. Anywayz, this being Hacked Gadgets, where’s the circuits and specifications so we can build this it ourselves?

layers of LCD. thats all I have to say.

This may be one of those projects that will take a bit of time before we can build it ourselves.

Yeah, how about a real open-air volumetric display. It’s still just layers of LCD, it’s not much of an accomplishment.

No, not layers of LCD
>The Media Lab’s video holograms appear to float above a piece of frosted glass.

I want one.

The MIT holographic displays are true on the fly generated holograms. This
is not about stacking LCDs or about some flickering rotating screen at 12
RPS. This is the real stuff where you can stick your finger in. Try that with
a rotating screen.

I didnt mean “this is layers of LCD” I ment ” somethin like this could be ACCOMPLISHED by layers of LCD”

joebob: lol, then how would you wave your hand through it?

[…] I found this on [hackedgadgets] and checked out the paper describing the project. I’m not sure if it will generate any truly usable graphics any time soon, but the technology is pretty interesting. It combines six video channels and uses acoustic frequencies and tiny but simple looking transducers to vibrate the crystal that channels a laser to generate the hologram. (If I read that paper correctly) Surprisingly, a single nvidia chip generates all six channels for the system. Annoyingly, there’s a lack of info on MITs site, but there’s a nice group of images under the multimedia link of this article. […]

Yah the same holographic effect has now been possible with the help of play station 3. I have saw a review on a video site about the playstation3. What all is been discussed here about holographic video is really interesting to know. Soon we all will be able to feel the virtual reality.
