Laser beam remote sensing involves using a laser beam to sense target objects from a long distance. The key technologies involved are the light source and the detector. Its primary advantages are high precision, large amount of information and compact equipment. Vehicle-mounted fiber laser radar is an advanced environmental sensing device that integrates the light source and detector. It plays a crucial role in the field of intelligent driving. It provides high-precision environmental sensing and multiple information parameters, including distance, angle, intensity and velocity, and has strong anti-interference capabilities.
