Possible! If you make a 3D hologram of a 2D plane, it will still be 2D, but at a particular depth location. This makes my head hurt to think about, though.

- hologram-paul 7y agoShould work, I think.
- dTal 7y agoA traditional analog hologram of a real plane, like a table, would simply recreate the image of that object exactly. It would have parallax just like the real thing. To engineer a hologram that makes some attempt at "following" you, you would either need an extremely elaborate multi-exposure analog setup with rails and shutters and god knows what, or a digital holographic printer, which is another (fascinating) kind of beast entirely. In the latter case you generate what you want the hologram to look like from every possible angle, which is your case is simply the same image with perspective (un)distortion.
- hologram-paul 7y agoThe 3D Hologram Printer we are building does exactly that!
- noyesno 7y agoWould it be possible to use light-field cameras like Lytro as source material?
- hologram-paul 7y agoYes, this would work well! Might have a more narrow viewzone, because the light field from those is fairly narrow as I recall.
