Holography

Holography refers to the area of photography that is dedicated to producing holograms and other three-dimensional images. Holography works by transferring an image onto film or photo paper with a laser and then developing it with laser or another light source.

This avenue of photography is also known as lensless photography due to the fact that it reproduces images without the aid of a lens. While physicist Dennis Gabors is credited with fathering holography in 1948, it wasn’t until 1960 that lasers were involved in producing three-dimensional hologram images.

The DVD laser is one of the most notable instances of how holography technology infiltrates our modern life. Similarly, refinements in holography lasers have made them accessible to low-budget researchers and artists.

Yet, while conventional modes of holography revolve around still, permanent images, new methods of creating dynamic holograms are becoming more popular. These dynamic holograms, also known as “real-time” holograms, that allow the information contained within the hologram to be updated frequently. Although real-time holography is not used extensively in the realm of photography, it is central to the aerospace and fiber optics industries.
