The important role of voice coil motor lidar technology in new infrastructure. The popularity of the term new infrastructure has continued to rise since the successful 2020"two sessions, " according to Baidu's COVID-19 search big data report, which was released on March 4, "New infrastructure" related to the search heat has increased significantly. So, "new infrastructure, " 

     "new infrastructure, " what exactly is new infrastructure? The opposite of the new is the old. The new infrastructure is based on the old infrastructure and enables the traditional industries to develop towards the direction of networking, digitalization, informatization and intelligentization, it includes the construction of 5G base station, industrial internet, Intercity high-speed railway and Urban Rail Transit, big data center, artificial intelligence and so on. 

     This shows that intelligent transport is an indispensable part of the new infrastructure, and intelligent transport is closely related to Lidar. On the one hand, Lidar can detect obstacles at a long distance and is not affected by ambient light; on the other hand, based on the analysis and processing of Lidar high-precision 3d point cloud data, high-precision positioning and map generation can be realized. 

        In addition, with the rapid development of autonomous driving and unmanned driving, Lidar will have a great leap forward, because unmanned driving is called the "crown" of artificial intelligence, and the laser radar that is used for pilotless is called"Pearl"on artificial intelligence crown. 

       When it comes to Lidar, did you know that voice coil motors have been used in some of these applications, where the technology of Lidar drives the new infrastructure forward, and the technology of Voice Coil Motors drives the technology of Lidar forward, in other words, voice Coil Motors will play an important role in the new infrastructure and demand will increase in the coming years. Laser radar is to send a laser beam, and then receive the light beam reflected from a distant object, by measuring the travel time of the light beam to get the distance information of a distant object. However, laser beams are very narrow and they do not scatter, so a single lidar pulse can only sense a very small object. For practical use, lidar sensors have to undergo some form of "scanning" . Most Lidar sensors are connected to a drive motor that rotates them, and once the laser is synchronized with the motor's motion, we can tell where the laser is pointing and combine the whole image of the environment ahead. Therefore, the field of view of Lidar depends on the angle of rotation of the motor, which has been used to swing voice coil motor. 

     Kunshan has been working in the field of voice coil motors for more than a decade, tongmao voice coil motor includes five types: Cylinder Voice Coil Motor, rectangular voice coil motor, flat voice coil motor, swing voice coil motor and shaft voice coil motor.
