The large -scale application of the optical waveguide solution is expected to help AR realize the B -side move towards the C -side (below)

Although the Optical Wave Guide solution is restricted by factors such as process and good product rate, this does not prevent it from rapid expansion of the B -end market. Compared with the first three generations equipped with AR products with separate optical, prisms, and free curved schemes, light wave guide is used.Because the technology is the mainstream, because it is also more advantageous in the corner of the field, it has achieved a leap to the B -end application market.However, with the emergence of the technical barriers of this technology, the optical waveguide technology has gradually become a big problem in the industry to achieve the B -end to C -end.

In this regard, Wang Yaochang, a partner of Beijing Lingxi Micro -Light Technology, said that compared with the prism solution of the previous generation, the light wave guide solves many problems facing the AR in the prism era, especially in terms of visual effects.And the prism reflection technology has been improved many times, and it can achieve a larger FOV angle. These are not comparable to previous generations of technology.The main reason for the smaller angle of viewing and prism solutions is caused by the approximation of the near -axis considers of its optical design itself.In other words, after considering the approximation of the near -axis, the light reduction closer to the light shaft is higher, while the light far from the light axis is lower, so we can easily see the significant difference in image quality.The optical wave guide scheme has bypassed the approximation of the near -axis in the design and calculation link. Therefore, the light wave guide array we see can maintain the trait consistency of the light (large angle light) in different directions, therebyThe degree of restoration will not affect, and it can also meet the application of AR currently in the B -end market.

Su Bo, CEO of Shenzhen Augmented Reality Technology Co., Ltd., also revealed to reporters that although most of the current AR manufacturers are targeting the C -end entertainment market, they will actually start expanding from the B -end market.At present, the application market of AR is mainly distributed in B -end fields such as industrial, training, marketing promotion, and exhibition display.Take our company's products, our current main application scenarios are still in the industrial field, such as aircraft and automobile maintenance, power equipment detection, and maintenance of manufacturing equipment maintenance, and other B -end scenarios such as marketing promotion and training are compared to industrialIn terms of scenes, the size of the application is relatively small, mainly because these areas have more other replaceable low -cost solutions, so the demand for new technologies is not as large as the industrial field. Therefore, the current B -end market is still in industrial applications.Mainly.

In the industrial field, Su Bo further added that traditional ERP systems and E-Learning systems have been unable to adapt to current application scenarios such as intelligent production, manufacturing, maintenance, and training.Because the front -line employees cannot liberate their hands, they can hardly use the Internet and information technologies, and managers cannot manage the work details of front -line employees; traditional corporate face -to -face and online training cannot solve employees' time.Dilemma, these are the current pain points of the industrial application field, so it also constitutes the rigid needs of industrial scenarios for AR technology.At present, we have cooperated with multiple enterprises in the areas of aviation maintenance, automobile maintenance and training, power inspection, and military inspection, and military applications.High.

In response to the technical requirements of whether AR devices currently adopted by optical waveguide technology can match industrial application scenarios, Su Bo said that the industrial field still has certain requirements for the FOV of AR products.The corner of the field is generally small, and the maximum can only achieve about 20 °. This obviously cannot meet the application requirements of the industrial field. As a result, AR has not obtained a certain scale application in the past few years.Today's Optical Byegua reflection technology solutions can make AR's viewing corners of about 30 ° to 40 °. Foreign Lumus can achieve about 55 °, and it is not a problem to meet the requirements of the industrial field.

Unlike VR, AR's FOV is not only difficult to get further expansion, but even the current light waveguide solution is almost impossible. Therefore, it can only be regarded as a night to the C -end.In this regard, Wang Yaochang said that the FOV that the existing Optical Wave Guide solution can reach is limited. From the perspective of the current level, the highest viewing angle of the optical wave guide solution can only reach about 50 ° to 60 °, and thenIt is impossible to expand upwards. This is the technical barrier that is difficult to pass by the solution itself.However, this also conforms to the law of the change of the AR optical solution. With the decline of separation, prism, and free curved schemes, optical wave guides have become the leader in this time.Some new popular schemes are replaced.But for the time being, Overwhelming will continue to prevail in the AR field.

Su Bo agreed to this that if you want to achieve a larger FOV, it is impossible to use the existing light waveguide technology. Therefore, there are some other leading companies such as Magicleap and Microsoft in the industry to start studying new AR optical solutions.To achieve a larger FOV expansion.However, in terms of the current situation of the optical waveguide solution, it is unrealistic to FOV to reach 90 ° or more, but this also creates opportunities for the emergence of the new generation of technical solutions.

The light field plan may still need to solve miniaturization problems if they will break the deadlock

As mentioned above, with the gradual steps of the optical wave guide technology, coupled with the rapid growth of the C -end market for AR demand, some companies have begun to seek new technical solutions to break the deadlock.The industry, such as Microsoft and Magicleap, are working hard to deploy a new generation of optical field technology.However, unlike Magicleap's optical fiber array display, Microsoft uses the mode of optical waveguide+light field combination to further improve the HoloLens's field of view. At present, the relevant patent has been disclosed, but it takes a certain amount of time to really land.Although Maigcleap uses the optical fiber array display technology, due to the large amount of data data and the amount of calculation, there is also controversy in the miniaturization of the technology.

In this regard, Su Bo said that the current optical field technology has begun to emerge and has achieved a breakthrough in the application of laboratory levels. However, due to the high requirements for calculation and many other aspects, Magicleap has not given the actual situation.product.But according to the news from my friends in Silicon Valley, Magicleap's main problem is currently the overall volume of the device, and the AR headset display is almost the same as the perm machine we see in the barber shop is so large, so it is miniaturized.There is also a long way to go.

Shenzhen Optical Field Visual Co., Ltd. COO Zhao Qingquan said in an interview with Huaqiang Electronics that although it takes a certain time to really land, compared with the optical wave guide plan, the optical field technology does not have FOV limited problems such as FOV.The FOV of the optical field technology can theoretically expand infinitely, and ultimately it can reach the level of the full perspective. This is an advantage that it does not have by the optical wave guide and prism solution.And I think that in the next 5-6 years, optical field technology can expand the angle of AR to about 180 degrees, which is obviously an explosive opportunity for the C-end market.

Although optical field technology is not as popular as the optical wave guide, from the perspective of technological development period, optical field technology and optical waveguide technology are still in the same development period.Zhao Qingquan added that the light field technology is not so popular in the industry, mainly due to the difficulty of the realization of light field technology and the high technical threshold. Not many domestic enterprises have the ability to engage in the research of technology and the implementation of the corresponding products.However, with the increasing improvement of the level of optical field technology research in the industry, miniaturization problems will also be gradually solved, and replacing the existing light waveguide solution is also the mainstream in the field of AR optics technology.At that time, AR and VR will be integrated, the two -way conversion can be achieved, and the application market of the AR/VR can be fully opened.
