What are holograms?
How do holograms work?
Holograms work by splitting a laser beam into two parts. One part, called the reference beam, is directed straight onto a photographic film or plate, while the other part, the object beam, is reflected off the object to be pictured and then onto the film. When the two beams meet, they create an interference pattern that is recorded on the film, resulting in the hologram image.
