The reasons for lidar systems utilizing the 905nm and 940nm wavelength bands are primarily as follows:
Firstly, for the 905nm band, laser light at this wavelength exhibits strong scattering and absorption capabilities in the atmosphere. This characteristic makes 905nm lidar safer for short-range ranging and obstacle avoidance applications, as its illumination distance is relatively shorter, thereby satisfying, to a certain extent, the safety regulations for laser products. Furthermore, lidar operating in the 905nm band is not subject to particularly stringent restrictions and regulations in some regions, which also provides greater convenience for its practical applications.
Please note that while the above provides a general explanation, the specific technical choices may vary depending on different LiDAR manufacturers and application scenarios. Therefore, in specific applications, it is recommended to refer to relevant technical documentation or consult professionals for more accurate information.
