What do flying cars, time machines and holograms all have in common? They’re future technologies that the world never thought they would see brought to life. This was until holograms were created. When talking about holograms, the first thing that usually comes to mind is their use in the entertainment industry for things like 3D movies and recreating musical artists. But, holograms actually have more uses than people would think. Some examples of occasions when holograms are used are for security, authenticity, and tracking. In the future, we can expect to see holograms in households, and with the proper technology, we might even see them on our smart phones, too!
In the 1940’s Dennis Gabor, a Hungarian-Brit, invented holography. He won the Nobel Prize in 1971 for the “invention and development of the holographic method.” It started out as wanting to improve electronic microscopes when Gabor stumbled upon holography. (Hubbard, 1995). He decided to call the invention holography because it is comprised of the two greek words “holo” and “graphy.” The word “holo” means “whole” and “graphy” means “writing/pictures.” Later, with the invention of lasers, optical holograms became possible. In 1964, at a conference of the Optical Society of America, Emmett Leith blew everyone’s minds when he introduced holograms with lasers which made 3D holograms possible. From that moment, holograms became commercially available (Schwartz, 2006). The recording of holograms is a lot like taking a photograph. First, you focus on what you want to take a picture of. Then, inside the camera, when you press the button to capture the photograph, the shutter flicks and allows light in. The film inside is exposed to this light and the field of view imprints on the film. Later, after the film is developed using specific chemicals, you are able to see what was in the original field of view. For
