Domestic mass production of passenger cars in the use of voice coil motor lidar made a key step

     Domestic mass production of passenger cars in the use of voice coil motor lidar made a key step. According to a news report on September 3, the laser radar ranging module developed by Beixing (Beijing) photonics Technology Co. , Ltd. has been successfully used in a mass production project for a brand SUV passenger vehicle by passing relevant class standards. 

     So how does the LIDAR ranging module work in an SUV passenger car? It is reported that in the SUV carrying the North Wake Lidar, the Lidar System through the optical signal detection, built-in chip to calculate the distance value, as long as the distance value within the set range, can determine whether the car owner in the trunk open position, realized from the wireless remote control trunk, to the Intelligent Sense boot boot boot boot innovation. 

      Speaking of Lidar, Voice Coil Motors are now a core component of advanced lidar, which emits a laser beam and then receives light reflected from a distant object, the distance information of distant objects can be obtained by measuring the time of flight of the light beam. 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 a lidar depends on the angle at which the motor is rotated.
