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.
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]
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.

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 ...
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 ...
A holographic display is a type of 3D display that utilizes light diffraction to display a three-dimensional image to the viewer. Holographic displays are distinguished from other forms of 3D displays in that they do not require the viewer to wear any special glasses or use external equipment to be able to see the image, and do not cause a vergence-accommodation conflict.
Augmented Reality (AR) experiences integrated with holographic displays are driving impressive 35% click-through rates, with thousands of customers engaging in the first two weeks of campaigns. “Today’s consumers live in a world where engaging with 3D experiences is becoming second nature,” said James Andrew Felts, CEO of HMN.
Blade Runner Style Holograms. This is why I came to CES. This is the shit I want, like the Blade Runner 2049 meme. The London-based software company Hypervsn made a splash on the Las Vegas ...
