Do actual holograms that pop out and seem like a transparent object exist?
Assuming you really mean hologram: Popping out? Yes. By controlling the optics (and thus the interference patterns from which a hologram is reconstructed), you can create 3d images that appear to be behind the surface of the hologram film, in front of it, or crossing through it. I have a small hologram magnet on my fridge which produces an image that appears to extend through its surface. But since what you’re realy seeing is two different flat images at the hologram’s surface, the floating portion has to be in front of the hologram — if you move too far to the side, part of it gets cut off. Basically, the choices are just like those of a 3D movie. They can put the effects in front of the screen or behind it, in eactly the same way. But the image is always a matter of your two eyes both looking at the screen and seeing different views; there’s no way to move the image beyond the edges of the screen. This should also answer your question about transparency. If you make a hologram of a
