Light interference patterns are recorded
- In conventional photography, the light reflected off an object strikes a strip of film that contains a chemical (i.e., silver bromide) that reacts to light. This produces a two-dimensional representation of the subject. A hologram forms a three-dimensional image because light interference patterns are recorded, not just reflected light.

Mar 10, 2021 · MIT researchers developed a way to produce holograms almost instantly. The deep learning-based method is so efficient, it could run on a smartphone, they say.
Holography is a technique that enables a wavefront to be recorded and later reconstructed. It is best known as a method of generating three-dimensional images, and has a wide range of other uses, including data storage, microscopy, and interferometry. In principle, it is possible to make a hologram for any type of wave.
Mar 13, 2024 · Holograms are three-dimensional images created by recording and reconstructing the light reflected from an object. This technology uses laser light to capture the light field an object emits, which it presents in a way that mimics the original object’s appearance.
Aug 30, 2023 · There are two basic categories of holograms — transmission and reflection. Transmission holograms create a 3-D image when monochromatic light, or light that is all one wavelength, travels through them. Reflection holograms create a 3-D image when laser light or white light reflects off of their surface.

Optical holography[1] is a technique which enables an optical wavefront to be recorded and later re-constructed. Holography is best known as a method of generating three-dimensional images but it also has a wide range of other applications.
Sep 21, 2021 · When the beams meet on the holographic film, they create an interference pattern that is specifically coded through this process, to produce a 3D holographic image of the object. Although this represents a simplistic version of the physical phenomena happening, it can give non-physicists a good idea of how the process of creating a hologram ...
