During Tuesdays CNN coverage of the US Election, anchormen Wolf Blitzer and Anderson Cooper conducted live interviews "via hologram". Blitzer told CNN reporter Jessica Yellin that "You're a terrific hologram," during a segment where he spoke with a 3-D representation of Yellin, or so it would appear. Okay, I'm envisioning you reading this quote in a Simpson's Comic Book Guy voice..."They were quite sophisticated, no doubt," said Hans Jürgen Kreuzer, a theoretical physics professor at Dalhousie University and an expert on holography "But I immediately said to my wife that I don't think it has anything to do with holograms."
Kreuzer believes the images were tomograms or images that are captured from all sides, reconstructed by computers, and then displayed on screen much like the way that computer-generated special effects are added to movies.
Holograms, technically, are projected into space.
