Holographic optical element is a device that uses the principle of light interference and diffraction to record and reproduce the light field. It can record the information of three-dimensional objects in the light field and reproduce it by the diffraction of light. Holographic optical elements have the advantages of high resolution, large field of view and strong sense of reality. Binocular holographic display technology is a technology to achieve realism by simulating the parallax effect of human eyes. Among them, the binocular parallax refers to the parallax effect caused by the difference of the line of sight position when the human eye observes the same object through the left and right eyes. In the binocular holographic display, the light field information at different parallax angles can be simulated by using holographic optical elements, thus the stereoscopic presentation can be realized.

It is reported that the binocular holographic display technology based on holographic optical elements studied by NASDAQ:WIMI is the combination of holographic optical elements and binocular imaging technology, which can realize the possibility of viewing holographic images without any additional equipment. This technique makes use of the principle of binocular imaging, by projecting images from two different perspectives onto holographic optical elements, and then synthesizing the images into a stereoscopic image through the effects of interference and diffraction. so that the viewer can see the real stereoscopic effect in space.

The data show that the binocular holographic display based on holographic optical elements is a new display technology, which uses holographic optical elements to achieve binocular stereoscopic display. Compared with the traditional binocular stereoscopic display technology, it has the advantages of strong stereoscopic sense, strong sense of reality, large field of view and good optical effect. The traditional binocular stereoscopic display technology usually uses split-screen or interlaced mode to display the images of the left and right eyes, while holographic optical elements can bring the information of the two perspectives to the eyes of the observer at the same time, so that users can see different stereoscopic images at the same time. Viewers can more truly feel the three-dimensional sense of the objects in the image and enhance the user's sense of immersion and participation.

Previously, the traditional binocular stereoscopic display technology usually requires the images of the two viewing angles to be displayed on different screens, so the observer can only watch the stereoscopic effect in a fixed position. On the other hand, the holographic optical element can simultaneously bring the images of two visual angles to the eyes of the observer, which can provide a larger viewing angle, so that the observer can obtain stereoscopic effect in a wider range, and the image will not be distorted in different positions. In addition, the binocular holographic display of micro-beauty holography (NASDAQ:WIMI) based on holographic optical elements can achieve better optical results. The traditional binocular stereoscopic display technology usually requires the use of glasses or other auxiliary devices to achieve stereoscopic effects, which may cause optical distortion or weaken the clarity of the image. The holographic optical element can directly produce the stereoscopic image, which avoids these problems and makes the image more clear and real.

Holography has always attracted much attention and has a wide application prospect in various fields. In the aspect of binocular holographic display, the technology based on holographic optical elements of WIMI micro-beauty holography further expands its scope of application. Through the use of holographic optical elements, we can achieve a more realistic and realistic effect of binocular holographic display, and bring users a more immersive experience. This technology has great application potential in virtual reality, augmented reality, electronic games and other fields. For example, in virtual reality, binocular holographic display based on holographic optical elements can provide a more real virtual environment, bring users a more realistic experience, and enhance users' sense of participation and immersion. In the aspect of augmented reality, the binocular holographic display based on holographic optical elements also has a wide application prospect. By combining the virtual image with the real world, users can see the virtual object in the real environment and interact with the virtual object.

In the future, with the continuous progress of technology, the manufacture and design of holographic optical elements may become more refined and advanced. This will enable the binocular holographic display device to provide higher resolution and fidelity, so that the viewer can get a more real and immersive experience. It can be predicted that the binocular holographic display technology based on holographic optical elements of WIMI micro-beauty holography will be applied in more fields, promote the innovation and development of related industries, and bring more convenience and innovation for people.
