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.
