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. [ 1 ]
It is possible to make holograms of much less stable objects by using a pulsed laser which produces a large amount of energy in a very short time (μs or less). [7] These systems have been used to produce holograms of live people. A holographic portrait of Dennis Gabor was produced in 1971 using a pulsed ruby laser. [1]: Figure 4.5, p44 [8]
In principle, it is possible to make a hologram for any type of wave. A hologram is a recording of an interference pattern that can reproduce a 3D light field using diffraction. In general usage, a hologram is a recording of any type of wavefront in the form of an interference pattern.
Now, researchers from Brigham Young University (BYU) have created a true 3D hologram, or "volumetric image," to use the correct term. ... So far, the only true color hologram we've seen come from ...

The holographic optical element is closely linked to holography (science of making holograms), a term proposed by Dennis Gabor in 1948. Since the idea of holography came around much has been done over the next few decades to try and create holograms.
Digital holography is the acquisition and processing of holograms with a digital sensor array, [1] [2] typically a CCD camera or a similar device. Image rendering, or reconstruction of object data is performed numerically from digitized interferograms. Digital holography offers a means of measuring optical phase data and typically delivers ...
Paint 3D is a retired raster graphics and 3D computer graphics application which is a refresh of Microsoft Paint. [2] It is one of several 3D modeling and printing applications (formatted under 3MF) introduced or improved with the Windows 10 Creators Update, including View 3D, Windows Mixed Reality, and Holograms, along with the CAD programs 3D Builder and 2D Builder.
