Zusammenfassung:	A ranging light source includes a light source, a frequency division device and a transmitter. The light source is configured to generate a comb laser. The frequency division device is configured to generate a plurality of emitting n laser beams. These emitting laser beams have different center frequencies respectively. The transmitter is configured to output the emitting laser beams. The light source, the frequency division device and the transmitter are located on a first optical path. On the optical path, the frequency division device is between the light source and the transmitter.
