What is Holography?
- Holograms are virtual three-dimensional images created by the interference of light beams that reflect real physical objects.
- To produce an accurate visualization of a hologram at a certain point in space
- Needs two light waves to be coordinated in motion - a reference wave and an object wave. Both are formed by separating the laser beam.
- Reference wave is created directly by the light source,
- Object wave is reflected from the recorded object.

Dennis Gabor 1947
In 1947, Dennis Gabor — a Hungarian-British physicist — developed today’s modern hologram theory while working on an electron microscope. However, optical holography didn't really advance until the advent of the laser in 1960. A laser emits a potent burst of light that only lasts a few nanoseconds.
