This Peking University science man makes AR glasses "to win" Microsoft

When Zhongguancun Cube met Zheng Zheng, the book was angry. He is holding a paper-and-pencil computer in his hand, like a science and engineering boy who is common in college campuses. He can't see that he has graduated from the society for almost two years.

Zheng Zheng, born in 1987, graduated from the Northern Institute of Electronics Research. He called himself the kind of person who wants to do something interesting.

Zhizhi noticed his fascinating gleam technology (hereinafter collectively referred to as "spiritual rhinoceros"), which was recently published as a prototype of the optical scheme released by Beijing Lingxiu Micro-light Technology, using optical waveguide technology and nano-scale coupled grating technology. The 32° and 1.7mm thick lenses have attracted the past. In this 20-person company, technicians accounted for 15 places, and the core team was born in Tsinghua University. So, how did they make AR lenses so thin? ——Intelligent things bring the road of pursuit of its founder & CEO Zheng Zheng on AR today.

Graduation is entrepreneurship, young is capital

After graduating in 2014, Zheng Zheng began the road to entrepreneurship. At the time, the concept of AR was far from being hot, and the concept of smart devices was the limelight.

The interest in AR stems from the launch of Google Glass in 2012. In this version of the glasses, there is also the concept of smart devices, which also represents a new way of interaction and information presentation, but "Google glasses were doing very bad at the time, I want to I made the look of AR glasses in my mind."

Zheng Xiao said that when he was a child, he felt that people should do something that can affect or change the world in their lives. "Everyone will think that this person has brought something to the world for the society, whether it is good or bad, not meaningful. This will make me feel rich in life." He paused. "But this thing has been ruined."

From the start of the business to the present, Zheng Zheng is doing technology-related, and now more control. He believes that his strength lies in "concentration". If you are interested in this matter, you will be involved in it, feel meaningful and happy, do it, and don't think too much.

At first, among the core team of Confucius, three were doing technology and the other was responsible for the market. One of the other two people who are doing technology is Zheng Xiao’s classmate. “He was next to the lab. When I had this idea, I called him together. He was also moved and felt very good. He came together. ""

Zheng Wei is responsible for controlling the technical direction, and his classmate Wang Yaozhang is doing specific technical implementation.

"My two technology partners are very good." ——The technical partner of Zhejiang University used to be optical, with strong execution and deep knowledge in optics; the lab students have strong hands-on ability and can always put things that seem impossible, and can solve some practical problems. The problem in the experiment.

By mid-2015, the core team had added two people. Among the core teams of these six people, three are from Peking University, one is from Tsinghua University, and one is from Zhejiang University.

In addition, there are some members of the team from companies such as Google, LVMH, and ADA.

“Young is one of our strengths,” added Zheng Zheng. Most of the team members are young people who graduated soon. They have strong ability to accept and understand new things. They all have certain technical backgrounds and professional qualities. The technology iterative ability is suitable for the emerging industry of AR.

For traditional mobile phone manufacturers such as Huawei and Xiaomi to enter VR, Zheng Zheng also recognizes their advantages in supply chain resources, cost and capital. However, in the definition of products, Zheng Xiao feels that the small team seems to have more advantages - "In a specific technical breakthrough, big companies do not necessarily have advantages over start-ups. How to make real products, they are not big. Advantage."

In addition, Zheng Hao and the big companies feel that their understanding of the core technology, there is no thorough start-up company. In the breakthrough ability of core technology, the cutting-edge technology is not so good--easy to be limited by existing experience and framework, forming inertial thinking, difficult to break through, and self-restraint. "Technology is not enough to do."

Focus on AR optical display technology

Hololens, currently in the leading position in the field of AR glasses, uses holographic waveguide display technology, its optical lens thickness is 3-4mm, the field of view has 26 degrees; Meta Pro, using 3D holographic HD display technology, provides binoculars 40 The field of view of the lens is almost three times that of the 14° field of view of Google Glass, and the lens thickness is 2 mm.

It is understood that in the prototype of the self-developed optical scheme released by Lingxiu for a period of time, the optical waveguide technology and the nano-scale coupled grating technology are used to make the field of view angle of 30 degrees, the binocular field of view display resolution of 720P, and the light transmittance of over 90%. It can be adapted to the AR glasses model of myopia lenses. More importantly, the thickness is only 1.7mm, which is thinner than the former two.

Why did Microsoft and Meta, both with funds and talents, fail to do so thin, but did the pioneering spirits do it? In this regard, Zheng Zheng said that each person's definition of the product is different, perhaps they are not so concerned about the thickness of the glasses, so did not use too much thought in this regard. He later added that this is only his own guess.

Zheng Wei said that Lingxi is mainly committed to the core technological breakthrough of AR glasses - these technologies are the key factors in the AR application/consumer market. Specifically, they reduce the weight and volume of the AR glasses, expand the field of view and display area, and improve the display. The prototype that has been made so far has a weight of 100g and an angle of view of 32 degrees. At the end of the year, they will launch a second-generation prototype with their own core optical technology lenses – the viewing angle will be around 40 degrees and have a full AR function.

However, Israel's Lumus took the first step. The OE-32 smart glasses optical solution, which had been launched before, had an angle of view of 40 degrees, a thickness of 1.6mm, and a light transmittance of 78%, and has been supplied to customers in batches. However, Lumus also said that due to processing and cost constraints, consumer-oriented products will not be available until 2018.
