The application of LIDAR technology covers many fields, such as military, environmental science, aerospace, archaeological research, architectural measurement, robots and so on. At present, it is facing the great opportunity of autonomous driving. The LIDAR industry worldwide has been pursued by the capital, which not only attracts enough eyeballs, but also attracts large amounts of funds. The core components of LIDAR system include photodetector, laser, collimating lens, scanning mirror, digital-to-analog converter, etc. It is expected to attract well-known manufacturers, from key technologies such as laser light source, optical components and sensing technology, both domestic and foreign laser LIDAR suppliers, representatives of research institutions, industrial automation manufacturers, first-tier automotive suppliers and users of automotive OEMs, to participate.
