Abstract: A lidar system based on visible-near infrared-shortwave infrared light bands comprises a light source sub-system, a light receiving sub-system and a signal collecting and processing sub-system, and adopts a laser light source having a supercontinuum spectrum laser comprising the three bands of visible, near infrared and shortwave infrared light. The lidar system conveniently and effectively achieves hyperspectral measurement of three bands of visible, near-infrared, and shortwave infrared lights without needing to replace the laser light source, increasing the capability of detecting target spectrum information and application range, providing more accurate measurement results and post-processing algorithms, and strengthening the capability of simultaneously detecting visible-near infrared-shortwave infrared ligh bands of a lidar system.
