I've used a Looking Glass and it doesn't look like a a lenticular display. It looks closer to a hologram (despite the fact it's not.)
The image appears suspending inside the block of glass and responds sufficiently well to head movements to be convincing. You can't see the giveaway "ruled lines" that lentincular sheets have.
Once you know it's not truly holographic it becomes fairly obvious and you notice that up/down doesn't provide any depth (only left/right) but the effect is convincing and magical at first.
So although it might be lenticular in principle - it's far from what you could achieve with your proposed method.
Thanks for the information -- this was one of the concerns I expressed in a previous comment. It's going to be very difficult to evaluate this product via video. The videos/animations look so good that I had a hard time believing that the display performs that well in-person[0].
I can understand how this might really look a bit better, now, with the clarity on the left/right vs up/down depth (I recall reading something about depth perception that makes this less important, but I don't recall where/when), so it's sounding promising.
[0] I'm not saying it doesn't -- this is just based simply on the fact that I have yet to see one that does (and, in fact, if this isn't the technology I think it is, I haven't seen one at all).
Is not really my proposed method, it’s just how I understood them to work. IIRC they had a diagram with the original models that showed the lens, and also labelled things like a diffuser, etc. I’m not sure how much the technology has changed since their last generation.
