Abstract: A lidar system includes: light sources generating light of a linear light source type; a light emission unit including a diffractive optical element disposed ahead of the light sources and separating incident light from the light sources into point light sources, and a scanner moving the light separated by the diffractive optical element, and radiating light of a point light source to an object; and a reception sensor converting light received after reflection by the object into an electrical signal. Spectrum angles of point light sources that have passed through the diffractive optical element may be different according to a position of the diffractive optical element. According to the lidar system, an autonomous vehicle, AI device, and/or external device may be linked with an artificial intelligence module, drone ((Unmanned Aerial Vehicle, UAV), robot, AR (Augmented Reality) device, VR (Virtual Reality) device, a device associated with 5G services, etc.
