When A Hologram Isn't Really A Hologram

CNN made waves on Tuesday night by incorporating three-dimensional holograms into its coverage of the U.S. election. The only problem was, they weren’t really holograms.

“They were quite sophisticated, no doubt,” said Hans Jürgen Kreuzer, a professor of theoretical physics at Dalhousie University and an expert on holography who watched the 3-D interviews. “But I immediately said to my wife that I don’t think it has anything to do with holograms.” …

The CNN anchors were not really speaking to three-dimensional projected images, but rather empty space, Kreuzer said.
