Holographic projection technology is a popular black technology in recent years, which uses the principles of interference and diffraction to record and reproduce the real three-dimensional image of an object. Generally speaking, plane objects are three-dimensional, static objects are dynamic, and single-sided objects are polygonal. Therefore, holographic technology can also be regarded as the reconstruction and reproduction of the recorded image, which is a 360-degree phantom imaging relative to human vision, that is, people can see the omni-directional dynamic picture of the object in any direction. Because of breaking through the traditional limitations of sound, light and electricity, space imaging has bright colors, high contrast and clarity, and strong sense of space and perspective. Holographic technology can not only create three-dimensional illusion in the air, give people a closed visual impact, but also allow the audience to interact with the scene and gain a unique visual experience.
