I got this idea a little while ago, and I couldn't see any real flaws with it.
I figured out a way that you could create full 3D holograms.
If you have ever been to some pointless-technology shop like the Sharper Image, you will have seen some of those little clocks that had a small stick with LED lights on the end. The stick quickly waves back and forth, and the lights blink at specific times to create a floating image of the current time.
Like this:

My idea, is to set up a large grid of lights, and put a motor at the bottom. Like this:

The grid would spin vertically, and the lights would blink accordingly to create a 3D image. The more lights you add within the grid, the higher quality of a hologram you will create.
I'm suprised that it doesn't seem like people haven't tried this yet. [URL="http://www.youtube.com/watch?v=oLygWkHo9nw&feature=related"]People have created projected globes using this method[/URL], but that only uses an arc of lights, rather than creating not only the globe, but everything within it as well. With this method it seems like holograms would be rather easy to create.
We already have this, and the picture quality is shit.
also I don't like the idea of my holo-tv being able to decapitate me when I try to switch the channel manually.
That motor would have to spin pretty fast for it to look real. Plus i don't understand how the actual 3d concept would be applied. The lights would have to change at light speed (hardy-har-har) for you to actually to be able to see all around the hologram

Really? Is there a video anywhere?
And you could give it a glass case around it. TV's have glass faces to protect the lights.

The motor would need to spin quickly, sure, you could just have a lightweight grid. And what the hell are you talking about lights changing light speed?

No. I mention that video in the OP. That was just done with an arc of lights, so it could only project a hollow globe, nothing else.

The lights would only display in one direction, or if you tried to see it from another side then they would have to be tons of lights displaying all of the possible combinations of images.
Also, a spinning motor twirling this thing around is going to be hell for noise. I mean, it isn't going to sound like a lawnmower, but it will be annoying enough to not want it.
I laughed.
Rate op funny.
Didn't CNN do a Hologram during the presidential election?

I remember on some science show, they had a combination of OP's idea with the globe thing. It was used for 3d x-rays, and could be manipulated, i think. I also think it had Michio Kaku in it.

I have one of those
It's fucking BRIGHT, impossible to sleep with
They already have holograms. Done by projecting a duo of scanning lasers through two LCD screens.
hand fans do this.
Well, holograms would need to be hollow.
Especially if they become interactive, you need to be able to touch the image without a whole grid of hot LEDs smacking into your hand.

[quote=WIKIPEDIA]Though holography is often referred to as 3D photography, this is a misconception. A better analogy is sound recording where the sound field is encoded in such a way that it can later be reproduced. In holography, some of the light scattered from an object or a set of objects falls on the recording medium. A second light beam, known as the reference beam, also illuminates the recording medium, so that interference occurs between the two beams. The resulting light field is a seemingly random pattern of varying intensity which is the hologram. It can be shown that if the hologram is illuminated by the original reference beam, a light field is diffracted by the reference beam which is identical to the light field which was scattered by the object or objects. Thus, someone looking into the hologram "sees" the objects even though they are no longer present. There are a variety of recording materials which can be used, including photographic film.[/quote]
What you are describing may *SOUND* like a hologram, but it's more of a 3D image created by a bunch of rotating beams, that would be dangerous to have on a larger scale. AKA you'll get hit by your TV all the time.
What i copy-pasta'd is a HORRIFFICALLY simplified theory behind holography, and from what i understand, that is explaining a theory for making a kind of holographic tape for a projector TV of sorts.
[b]MY THEORY[/b]
A computer renders some 3D stuff [say some Gmod on a server], and then in it's rendering it takes the camera's view angles, takes the reflections from certain angles, and diffracts them with the reference beam. Once the "hologram" has been created, it gets sent to the projector...
MY PROJECTOR works by decompiling the data, and feeding it through a set of RGB lasers. Now RGB lasers DON'T EXIST, but in my theory, there will be a mass of standard lasers on a rotator, similar to what the OP describes, but different. There is a motor, with a rotating set of 6 poles on it. These have masses of lasers on them, about 64 on each pole (at this stage), 128 in total for EACH COLOUR. The lasers will flash in sync like the clocks do, but all of the colours work together to project 384 beams of laser light, in all colour, upward through a lens. (NOTE that the rotator is 128mm in diameter, so there is an LED for every millimetre, and the lens is about the same)
The lens will enlarge the image, whilst still projecting it up. It is now a 64[b]cm[/b] wide volume of laser beams. The projector will have a set of LEDs on a face above the projecting lens, these LEDs will be in a pattern that coincides with the rotation of the laser diode's enlarged beam.
The LEDs will reproduce the reference beam, and the lasers will obviously be the reproduced reflected image. Through diffraction an image will be produced, but the projector will only have a resolution of 128x128x128 pixels, so it is very limited.

Opposed to spinning sticks, how about a rotating platter like a HDD? they spin fucking FAST yet are virtually silent.
My idea is to have no solid objects at all.
You have a small motor under a large empty space.
Tiny water droplets will be sprayed up from the bottom while a projector projects an image onto the water.It will only be able to do a solid wall of colour. So I think we should have several fans blowing small streams of air in bursts to create room for single droplets to go thourgh, leading to the possibility of u shaped holograms.Viewing is another problem. I decided that the projector will have to be mounted on a O shaped ring placed on an angle with a laser tracking were the person is standing, moving around acordingly to show different parts of the image as you move around. The last problem is the refracting and splitting of light I can only suggest using clear liquid that won't refract light.
The projector will have to show different parts of the image as varying intensity, as to create the ilusion of depth.
That's my idea. What do you think?
I don't think holograms will ever get to a point where we see them in the movies. I can see holograms for basic 3d objects (which are already here in some sense), but true holograms that have live video wouldn't be practical at all. You'd need a camera shooting so many angles all at the same time. There was a video with some live video hologram type stuff showed off, but they only had 4 or 5 angles of video, and it was projected onto 4 or 5 different screens. All of the ones that looked really impressive were more illusions.

That globe in the OP looks a lot like a Star Wars hologram.
Sounds legit, but would have to spin pretty damn fast to project anything accurately.
this idea could have sucked a lot more than it did
:golfclap:
Feasible I guess..
