First of all, when it comes to the possible impact of lidar on human health, many people are worried about what to do if the laser hits the eyes? But in fact, the directionality of the high-frequency laser emitted by lidar is very good, and the divergence angle of the beam can even make To less than one ten thousandth of a degree, and the diameter of the laser beam of LiDAR is very small, it determines that the probability of a laser beam emitted by a LiDAR hitting the human eye is very, very low.
Moreover, in order to obtain ultra-high measurement speed, lidar usually uses pulse ranging technology, and the duration of each laser pulse is very short, less than 0.00000000001 seconds, which is picosecond level. Even if a small probability event occurs, it is only a short moment, and the laser has no time to cause damage to the human eye.
For LiDAR products, there is an important parameter index - "laser safety level". Take the C-Fans series of navigation obstacle avoidance lidars developed by Surestar as an example, each C-Fans meets the Class1 eye safety standard. In the International Electrotechnical Commission IEC/TS 60825-6-1999 Safety of Laser Products Part 6, the Class I eye safety standard is described as: Safety of products with optical sources, exclusively used for visible information transmission to the human eye.
That is to say, even if it is accidentally irradiated to the eyes, lidar will not be harmful to health. Class1 eye safety standard is not just talk!
Before leaving the factory, testers will take each lidar to go through the static test of the ground environment, field data collection, calibration and other links to ensure the data accuracy and stable operation of the product. Only LiDARs that have passed these tests will be handed over to customers to ensure the quality of the products to the greatest extent and provide end-users with a solid security guarantee!
In addition to the comprehensive and outstanding performance parameters, C-Fans is also the earliest front-mounted solid-state lidar with complete vehicle-specific design in my country! The "C-Fans" that have passed the IS016750 total of 31 tests in 9 categories have extremely high performance. Compliant with the car regulations, in severe cold and heat, high temperature and humidity, bumpy, It can work stably and normally in harsh environments. In this series, C-Fans -256 is the world's first vehicle-grade 256-line solid-state lidar, and another product, C-Fans32, is the only lidar product that has passed the "Intrinsically Safe" certification.
Although LiDAR will face various problems and difficulties on the road to help cars achieve complete self-driving. But none of these things will and should not affect our expectations for the future. As the world's leading lidar manufacturer, Surestar will continue to adhere to technology research and development and product polishing, solve all known problems before the products leave the factory, and provide professional and timely support services. Bring stability, efficiency and precision to customers' projects, and bring safe, fast and intelligent experience to end product users!
