The present invention provides a distributed laser radar. The distributed laser radar comprises an optical transmit-receive module, a plurality of distributed scanning units, and a distributed opticalfiber connection module. The optical transmit-receive module comprises a light source configured to emit detect light, and an optical receiving unit configured to receive detection light echo. The distributed scanning units are distributed at carriers of the distributed laser radar. The distributed optical fiber connection module is coupled to the optical transmit-receive module and the distributed scanning units. The detection light emitted by the light source in the optical transmit-receive module is coupled to the distributed optical fiber connection module, and is synchronously transmitted to the distributed scanning units through the distributed optical fiber connection module, wherein the distributed scanning units emit the detection light to a detection area through a scanning device and receive reflection light echo of the detection area, the reflection light echo is transmitted to the optical transmit-receive module through the distributed optical fiber connection module andreceived to the optical receiving unit in the distributed optical fiber connection module.
