Name: Alex W.
There used to be an arcade game that utilized a literal
hologram. A cowboy figure would stand in literal air, and shoot zombies
or something. I saw on the discovery channel how it worked: the image was
bounced off a curved mirror in such a way that the light entering each of
my eyes would be at a different angle. Can I hope to see a literal 3D TV
based on this technology in the next decade?
Does not sound like a hologram to me. The essential feature of a
hologram is diffraction.
