3D Television?

How about holographic 3D TV?

The Road to 3-D TV

1947
While working for the Thomson-Houston Electric Company in Rugby, England, Hungarian physicist Dennis Gabor invents the hologram, for which he is awarded the Nobel Prize in 1971.
1987
TI engineer Larry Hornbeck invents the digital micromirror device, an optical semiconductor used in video projectors and TVs starting in 1996.

2003
University of Texas Southwestern Medical Center researcher Harold Garner demonstrates the first holographic video-projection system, screening hazy red images of a helicopter circling a jet.

2008
The U.S. Air Force installs holographic head-up displays in fighter jets, bringing aviators 3-D images of battlespace positions.

2015
Holographic TV goes live with a pay-per-view satellite broadcast of the heavyweight boxing championship.

:smack:

I didn’t mean to imply that i invented it, so if it came out that way, i feel silly. Merely, that it had occurred to me to try it independently of any example I have seen that others may have done. Is there a name for this method?

I’d look it up, but my eye’s are now permanently crossed… I could only make this post by dictation.

(where’s the cross-eyed smiley?)

John Logie Baird demonstrated three dimensional television in 1928.

Remember the Fisher Price video cameras - the ones that recorded black and white pixelated images onto normal audio cassettes? Mike, one of my friends in college, discovered that if you duct taped two of those side-by-side, the distance of the lenses was very similar to that of human eyes. He ran a line from each of the cameras to two monitors: one displaying a red image, the other, blue. He set up two video cameras to record the images from the two monitors and then condensed those two images onto one screen, passed around the “classic” red and blue glasses, and there was some MyTFine Homemade 3D Teevee.
Why, yes, he was a video major.

I don’t have stereoscopic vision of actual solid, three-dimensional objects, so none of this stuff works for me (except holograms, of course). Even if we get holographic tv to really work, would it be worth the bother? Unless you plan to move around the room a lot while you’re watching, the effect would be wasted; and I can imagine it being disconcerting if a scene shifts from, say a close-up of a character’s face to a sweeping outdoor vista. Just seems like an unnecessary gimmick.

I remember the show mentioned in the OP. Somewhere I have that part of the broadcast on VHS.

It required no special glasses and looked like the effect mentioned in post #11. They said at the time that they were working on the jerkiness of the method and hoped to have it perfected soon. Nver heard about it again.

Wait, so real physical objects don’t look three-dimensional to you, but holograms do? That’s bizzare… I can’t think of any mechanism which could explain that. A good hologram should look indistinguishable from the actual object, no matter who or what is looking at it.

If he’s saying he doesn’t have the use of one of his eyes, then of course he can’t view anything stereoscopically. However, a hologram would still show its many angles by merely changing the angle it’s viewed from. In this sense it makes a 2D surface appear 3D, even with only one eye. But, it’s still not stereoscopic vision. If you had the use of both eyes, the distance between would change the angle enough so that both eyes would receive a unique angle.

Just wanted to clarify a little further:

Those with mono-vision looking at a hologram will have to constantly change their viewing angle to see the effect (or twist the hologram in their hand). Those with stereo-vision only have to sit still, and it will look 3D because each eye is receiving a slightly different angle. So, I think Baldwin might be under the wrong assumption to think you’d have to move around the room constantly for a holographic picture to work (unless, that is, you have mono-vision).

And yeh, It’d kinda be worth it to me :smiley:
