Holography is a technique which enables three-dimensional images, known as holograms, to be made. 

The process is similar to the method used to create photographs, except that rather than recording an image, holography involves capturing light fields. Two beams of light are created by the refraction of one light beam directed at a mirror. One beam of light is directed at the object to be documented, while the other illuminates the recording medium. The two beams come together to create an “interference pattern” on a photographic plate. The plate is then developed, and a laser light is projected through the hologram. The interference pattern scatters the light, creating a projected, three-dimensional, ghostlike image of the original object. 

The inventor of this process, Dennis Gabor (1900-1979), fled from Nazi Germany in 1933, and was invited to Britain to work at the development department of the British Thomson-Houston company in Rugby, Warwickshire. He became a British citizen in 1946, and it was while working at British Thomson-Houston that he invented holography, in 1947. He was awarded the 1971 Nobel Prize in Physics.
