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] When a hologram is printed onto a mask or film, it is then illuminated by a coherent light source to display the holographic images.
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]
"We can think about this image like a 3D-printed object," said BYU assistant prof and lead author Daniel Smalley. Researchers create 'true' 3D holograms by trapping particles [Video] Skip to main ...
The 3D image from a hologram can often be viewed with non-laser light. However, in common practice, major image quality compromises are made to remove the need for laser illumination to view the hologram. A computer-generated hologram is created by digitally modeling and combining two wavefronts to generate an interference pattern image.
Voxon Photonics' 3D holograms use similar displays to a 3D printer and then the human eye does the rest. The post Australian-based company launches device that can project 3D holograms appeared ...
The Proto Luma, Proto’s latest innovation, powers the HMN network. Designed for retail, the Luma is more compact and cost-effective than Proto’s flagship Epic, while still delivering vivid 3D holograms. Its integration with Proto’s proprietary AI Persona tools and RetailSage fleet management system ensures seamless operation at scale.

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.
