Product Introduction With the rapid development of LiDAR technology, LiDAR has been widely used in automotive autonomous driving and mobile LiDAR scanners. The LiDAR dedicated test board produced by Jingyi Optoelectronics can be used for target distance calibration of LiDAR, allowing LiDAR to more accurately determine surrounding faulty objects and their motion trajectories. The reflectivity commonly used for laser radar calibration includes three reflectivity levels: 10%, 50%, and 90%. If high calibration accuracy is required, more step reflectivity can be customized. Our company adopts independently developed technology and processes. The reflectivity of this diffuse reflection plate is 90%, and the size is 1500x1500mm. Other sizes can also be customized, all of which have nearly perfect Lambertian characteristics and stability, allowing the laser radar calibration to achieve the best testing results.
