Electronic speckle pattern interferometry (ESPI), [1] also known as TV holography, is a technique that uses laser light, together with video detection, recording and processing, to visualise static and dynamic displacements of components with optically rough surfaces. The visualisation is in the form of fringes on the image, where each fringe ...
The rainbow holography recording process usually begins with a standard transmission hologram and copies it using a horizontal slit to eliminate vertical parallax in the output image. The viewer is therefore effectively viewing the holographic image through a narrow horizontal slit, but the slit has been expanded into a window by the same ...
Acoustic holography is a technique that allows three-dimensional distributions of sound waves called sound fields to be stored and reconstructed. To do this, sound passing through a surface is recorded as a two-dimensional pattern called a hologram (a type of interferogram). The hologram contains information about the phase and amplitude of the ...
The AdS/CFT correspondence is often described as a "holographic duality" because this relationship between the two theories is similar to the relationship between a three-dimensional object and its image as a hologram. [25] Although a hologram is two-dimensional, it encodes information about all three dimensions of the object it represents.
Holography is the science of producing holograms; it is an advanced form of photography that allows an image to be recorded in three dimensions. Subcategories This category has the following 4 subcategories, out of 4 total.
Computer-generated holography (CGH) is a technique that uses computer algorithms to generate holograms.It involves generating holographic interference patterns.A computer-generated hologram can be displayed on a dynamic holographic display, or it can be printed onto a mask or film using lithography.

In strong interaction physics, light front holography or light front holographic QCD is an approximate version of the theory of quantum chromodynamics (QCD) which results from mapping the gauge theory of QCD to a higher-dimensional anti-de Sitter space (AdS) inspired by the AdS/CFT correspondence [1] (gauge/gravity duality) proposed for string ...
