- Holography - Wikipedia
Holography is a technique that allows 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

holography, means of creating a unique photographic image without the use of a lens The photographic recording of the image is called a hologram, which appears to be an unrecognizable pattern of stripes and whorls but which—when illuminated by coherent light, as by a laser beam—organizes the light into a three-dimensional representation of
- Holography - HyperPhysics
Holography is "lensless photography" in which an image is captured not as an image focused on film, but as an interference pattern at the film Typically, coherent light from a laser is reflected from an object and combined at the film with light from a reference beam

Holography is the process of producing holograms and, although they are recorded on photographic film, the process is quite different from normal photography Holography uses light interference or wave optics, whereas normal photography uses geometric optics
- Introduction to Holography - ThoughtCo
Holograms create three-dimensional images by using light interference patterns from laser beams Lasers make holograms because their light is coherent, meaning it has the same frequency and phase Holograms are used in arts, data storage, security, and were improved by lasers invented in 1960
- What is a Hologram? – Holocenter
Other methods of projecting and reflecting images are often described as holographic – or even misleadingly holograms, because they have an optical presence, spatial quality or iridescent colors In the past there was a clear distinction between holograms and other visual media
- Holography - an overview | ScienceDirect Topics
Holography captures the phase and amplitude of light reflected from, or transmitted through, an object In visual terms it captures ‘true’ three-dimensional space and any objects which are placed within that space
