What's the deal with holographic projection?

  Holographic projection As one of the future display technologies, it has been highly sought after. However, there is too much information about this technology, and we often see a fog, what is true holography and pseudo-holography, what is holography 3D ，什么是 Pebohr ’s fantasy, which is a bit dizzying. Today, I want to talk to you about this topic in a language you can understand.

　　 Holographic projection It can be defined as follows: Holographic projection technology, also known as virtual imaging technology, is a technology that uses the principles of interference and diffraction to record and reproduce the true 3D images of objects. In layman's terms, holographic projection is to first use optical technology to record the information of an object from various angles, and then present the information in a three-dimensional form to everyone. This three-dimensional visual presentation makes people feel that the object is around them, which is beautiful and breathtaking. The audience can truly experience the dual world of virtual and real. Let's briefly compare ordinary projection technology and holographic projection technology. Maybe we will understand after reading it:

　　Ordinary projection: Collects planar information, for example, when a movie is released, it collects planar information, and then presents it to everyone through a planar medium, such as a curtain or a wall. In this process, the information is collected and restored in a planar manner.

　　Holographic projection: Collects three-dimensional information, that is, it collects object information three-dimensionally, and then restores the information three-dimensionally to the audience. The ideal medium that can carry this three-dimensional information is air. There are currently three types of holographic projection technologies on the market: 360 degree holographic display technology, air projection technology, and laser beam projection technology. Among them, 360 degree holographic display technology works by projecting the image onto a mirror, and then rotating the mirror at high speed to produce 3D three-dimensional images; air projection technology uses water vapor to project images onto water vapor. Because the vibrations between molecules are unbalanced, three-dimensional images can be formed. Laser beam projection technology is when nitrogen and oxygen are dispersed in the air, 3D the image is projected into the air.

　　 Holographic projection The application of this technology on stage can not only produce three-dimensional illusions in the air, but also make the illusions interact with the performers to complete the performance together, producing a shocking performance effect. With the application of holographic technology, stage art and movie clips appear in the same space, showing the audience the innovation of world multimedia art, and the service industry needs a mass base, so attracting consumers to a large extent is the king. The application of holographic projection technology in this aspect has attracted people's attention from a new perspective and aroused consumers' desire to consume.

　　A holographic projection scene refers to a scene where the audience can see the illusion at the opening of the generator, which is a circle. The holographic projection system 3D projects the image in the air of the real scene, creating an atmosphere that is both illusory and real. The effect is peculiar, with a strong sense of depth, and it is difficult to distinguish between true and false. It is fashionable and beautiful, with a sense of technology; the top is transparent, and it is a true spatial image; the colors are bright, with high contrast and clarity; it has a sense of space and perspective, forming an illusion in the air; the middle can be combined with real objects to achieve a combination of image and real objects; a touch screen can also be added to achieve interaction with the audience. It can be made into a four-sided window as needed.
