What Is a 3D Holographic Projection?

3D holographic projection is a method of recording and reproducing real three-dimensional images of objects using the principles of interference and diffraction. It is a 3D technology in which viewers can see three-dimensional virtual characters without wearing glasses. ^[1]

Holographic projection

Holographic projection technology is a recording and reproduction technology that uses the principles of interference and diffraction to record and reproduce a true three-dimensional image of an object.

The first step is to use the principle of interference to record the light wave information of the object. This is the shooting process: the subject forms a diffuse object beam under laser irradiation; the other part of the laser is used as a reference beam to hit the holographic negative and superimpose the object beam Interference is generated, and the phase and amplitude of each point on the object's light wave are converted into spatially varying intensities, so that all the information of the object's light wave is recorded using the contrast and interval between the interference fringes. After the negative film with interference fringes has undergone processing procedures such as development and fixing, it becomes a Nolide hologram, or

3D animation is changing people's aesthetic attitude to the acoustic and electro-optical technologies of those traditional stages with this brand-new thing.

We often see a three-dimensional holographic communication technology in science fiction movies, which can project a distant person or thing into the air in three dimensions, just like the scene in the movie "Star Wars." In addition, with the development of science, all devices are miniaturized and refined, but display devices cannot match them. Human beings increasingly demand a new display technology to solve problems. The 3D holographic projection plays exactly this role.
