lidar chip is an essential product in the development of new energy vehicles and smart cars. On July 2, the reporter learned at the international conference on the development results of the all-solid-state OPA 2D/3D lidar chip hosted by Yangzhou Qunfa Heat Exchanger Co., Ltd. that the trial production of the Yangzhou qunfa all-solid-state OPA 2D lidar chip was successful. OPA The research and development of 3D lidar chips is also in progress simultaneously. At the conference, You Zheng, president of Huazhong University of Science and Technology and academician of the Chinese Academy of Engineering, and Dr. Yi Yasha, tenured professor of the University of Michigan and academician of the Optical Society of America, had an in-depth discussion on lidar chip technology.
Academician You Zheng pointed out that lidar is like human eyes. In addition to being a must-have for the development of new energy vehicles and smart car industries, it also has important applications in other industries. If it can be better industrialized, it will also drive More developments in the field of optoelectronics.
Dr. Yi Yasha believes that the development of chip-level photonics is boosting the development of artificial intelligence . The combination of photonics and artificial intelligence has great potential. Equipment and systems based on artificial intelligence, such as robots, autonomous driving, wireless Human-driven cars, drones, etc. will rely heavily on photoelectric chips such as laser radar to achieve intelligence and practicality.
The all-solid-state optical phased array (OPA) lidar technology announced by Yangzhou Qunfa this time is a new type of radar technology with waveguide control of beam pointing. According to Chen Haitao, the head of Yangzhou Qunfa technology, there are currently 4 main types of lasers on the market. Radar technical route.
The first is mechanical lidar. Its advantage is that the technology is relatively mature and has reached mass production. However, the disadvantages are also very obvious because there are a large number of mechanical parts, which are relatively large in size, high in cost, and poor in stability and durability. .
The second is MEMS lidar technology, also known as pan-mechanical lidar. Its advantages are small size, simple structure, and price is greatly reduced compared to mechanical radar. However, the assembly is complex, the lifespan is short, and it is difficult to mass produce. Scan angle is limited.
The third is Flash lidar technology. Because it does not have a dynamic scanning device at the speed of light, its system is stable and the refresh frequency is extremely high. However, it consumes a lot of energy and poses certain safety risks to operators. Therefore, usually Flash lidar It can only be used as an auxiliary sensor and cannot be used as a main sensor.
4 is the OPA lidar technology released by Yangzhou Group. Compared with the other three radar products, OPA lidar does not require mechanical rotation to scan the beam in space. It has fast response speed, strong flexibility and accuracy. High, low cost, small size, all-solid-state has obvious advantages in observing high-speed moving targets and tracking multiple targets simultaneously. Therefore, it has very broad application prospects in unmanned driving, robots, smart security, etc. At present, It is also recognized as one of the ultimate development directions of lidar technology in the industry.
all-solid-state is the industry-recognized technical route for automotive lidar sensors. Leng Jianqing, senior director of ams Osram Group and Application Center of Greater China and Asia Pacific, once said in an interview with a reporter from " China Electronic News " that solid-state is the development trend of lidar. "Compared with traditional mechanical scanning methods, all-solid-state lidar fundamentally makes the structure of lidar simpler." Lei Shuyu, CEO and chairman of Feixin Electronics, also said that all-solid-state lidar can fundamentally reduce the cost of The production cost of lidar has thus become the technical direction of lidar products in the next few years.
Yangzhou Qunfa has been working closely with the University of Michigan in the United States, actively deploying in the field of optoelectronic chips, and has been deeply involved in optical phased array (OPA) lidar chip technology for many years. It is understood that at present, Yangzhou Qunfa’s OPA 2D lidar chip is being marketed, and the research and development of OPA 3D lidar chip is in progress simultaneously. According to reports, Yangzhou Qunfa’s OPA 3D optoelectronic integrated chips can be widely used in driverless driving, smart security, robots, urban and traffic management, medical and other fields. The market prospects are extremely broad and the market size is huge.
Analog chip prices may go down unilaterally
TSMC will build four more 3-nanometer chip factories
"Cloud" and You will "core". Can chip manufacturers still sit still?
