Holograms are interference patterns generated by the interaction of a blank reference laser beam with a second beam that has been reflected from an object of interest.

ECONOMIST: Researchers can now broadcast moving holograms

To create a hologram, such as those typically seen on credit cards, a laser beam is split into two (an object beam and a reference beam).
