Recently, Huawei European experimental center and advanced photonic electronics center of the university of Cambridge jointly released a paper on AR holographic display, from which we learned that Huawei is developing an AR optical module for retinal imaging, which is characterized by the ability to achieve flexible focusing and 3D holographic display.
According to a new paper jointly published by researchers at Huawei’s European experimental centre and the university of Cambridge’s advanced photonic electronics centre, the company is developing an AR optical module for retinal imaging, which features flexible focusing and 3D holographic display.
The paper points out that when AR glasses have poor focusing ability, it is easy to conflict with the visual focus of human eyes and cause visual convergence adjustment conflict, and visual convergence adjustment conflict may cause visual fatigue, wrong depth perception, and even nausea and dizziness.
At present, some traditional methods can be used to avoid visual vergence adjustment conflicts, such as simulating visual adjustment clues and binocular visual differences to reduce focal length conflicts. Holographic display can solve these problems, but considering the high bandwidth requirements of real-time rendering of 3D images, it is still difficult to achieve a high enough hd picture quality. In addition, the field of view Angle of 3D image will be limited, and the current technology can bring the field of view Angle of ±4.9° to about 3.7 microns.
In addition to the above methods, the focal length of the optical module can be temporarily adjusted by an adjustable lens, or several adjustable focus planes can be provided. However, the bandwidth requirements of these methods are still not low, and the optical element size is also large. The AR head display developed by researchers can effectively relieve the visual fatigue and vertigo caused by the conflict of vision convergence adjustment in AR, which is not easy to cause nausea or visual fatigue.
Holographic projection principle is simply the use of optical principle, the image in the air, the three-dimensional effect. Holographic space projection screen is a new generation of display equipment, with high clarity, light resistance, ultra-thin, anti-aging and other incomparable advantages. By the molecular level of nano-optical components: holographic color filter plate crystal as the core material, the integration of nanotechnology, materials science, optics, polymer and other multidisciplinary achievements and processing technology, with organic materials, inorganic nano-powder and fine metal powder as raw materials, produced. The thin and light interior contains advanced precision optical structure to achieve high clarity, high brightness perfect development.
At present, the most commonly used light source of holographic projection is from the projector, because on one hand, the brightness of the light source is relatively stable, on the other hand, the projector also has the role of magnifying images, as a holographic projection display is very practical. Holographic projection technology brings beautiful images to the audience and introduces the audience to another world. Holographic projection technology has broken through the limitations of traditional sound, light and electricity. The spatial imaging is brightly colored, with very high contrast and clarity. It can not only produce a three-dimensional illusion in the air, but also make the illusion and the performers interact, together to complete the performance, to produce a stunning performance.
Holographic projection technology is a popular high-tech technology in recent years. Holographic stereoscopic projection is realized by the principle of polarization of light, that is, two projectors are used to project images synchronously, the polarization direction of polarizer in front of the two projectors is perpendicular to each other, so that the polarization direction of two polarized beams of light generated is also perpendicular to each other. However, when polarized light is projected onto a special projection screen and then reflected to the audience position, the polarized light direction must not change. The audience can only see the corresponding polarized light image through each eye of polarized glasses, thus producing stereoscopic sensation in the visual nervous system. This new interactive display technology will be decorative and practical integration, in the absence of images completely transparent, give users a new interactive experience, has become one of the most fashionable product display and marketing means. Now, people use holographic projection technology to show the fusion of culture and technology.

We are committed to using holographic technology to meet the entertainment and business needs of our customers and end users.
WIMI’s leading holographic AR content production capabilities are built around image acquisition, object recognition, automatic image processing and computer vision technologies. WIMI’s software engineering team and visual design team work closely together to continuously advance these visualization-related technologies and use them to design and produce innovative holographic AR content. Scene recognition and tracking can be performed in seconds by providing a real-time computer vision algorithm for accurate attitude estimation. This cutting-edge algorithm also allows microme to perform pixel-based visualization of photo-level true high-resolution rendering. Froth &Sullivan says that while most peer firms might identify and capture 40 to 50 pieces of image data in a given unit of space, the number of blocks that WIMI Holographic Cloud (NASDAQ:WIMI) can collect ranges from 500 to 550. WIMI’s image processing speed is 80% faster than the industry average, thus improving operational efficiency. In the scene reconstruction process, the automatic image processing tool can remove the noise and enhance the features of the original image, so as to create the best holographic AR design with industry-leading simulation degree.
WIMI’s business areas include film and television, performing arts, sports, tourism, business center, fashion and luxury, quality education. It can be said that the way of holography + cultural content to enter the market is to bring a subversive change for the whole entertainment industry, open up a new blue sea, but also for the relevant industries to find an incremental market, and seek the good situation of multi-win development.
The AR industry is attracting increasing attention from investors. As an industry leader, WIMI Holographic Cloud (NASDAQ:WIMI) has successfully completed some investor financing so far and enjoys the economies of scale brought by the reduction of unit output cost. The powerful ability of WIMI Holographic Cloud (NASDAQ:WIMI) to provide high-quality AR content can encourage customers to continue to adopt our AR technology.
