Pros And Cons of Solid-state Green Laser Pointer Radar
Green laser pointer radar, one of the core equipment of autonomous driving. Why there is no large-scale application in cars. The reason is that the price of tens of thousands of dollars is too high, even more expensive than test cars. At present, many lidar suppliers' products are very expensive, and mass-produced cars simply cannot be carried. In order to popularize and develop autonomous driving technology, solid-state lidar has become a new darling of the market. Today I will talk about the solid-state green laser pointer radar. See if it is stronger than the traditional laser radar.

At present, our common vehicle green laser pointer radar is basically mechanical. Its obvious feature is that it has mechanical parts that can rotate, such as Velodyne 64-line lidar on Baidu self-driving cars. Its advantages have been introduced in previous articles, we will not go into details, but due to the mechanical design also directly constitutes several shortcomings of the current lidar. First, the optical path is complicated to assemble and assemble, and the production cycle is long, resulting in high costs. Second, the reliability of mechanical rotating parts in the driving environment is not high, and it is difficult to meet the stringent requirements of vehicle regulations. Therefore, in order to reduce the cost of lidar and improve the reliability. To meet the requirements of vehicle regulations. The development direction of lidar naturally shifted from mechanical lidar to solid green laser pointers radar.
