The embodiment of the invention discloses a laser radar, an automatic driving system and a mobile device, the laser radar comprises a transmitter, a receiver, a beam splitter, a transmitting-receiving lens, a scanner and an extinction module, along the transmission path of detection light, the beam splitter is located at the downstream of the transmitter, the transmitting-receiving lens is located at the downstream of the beam splitter, and the scanner is located at the downstream of the transmitting-receiving lens; along the transmission path of the echo light, the beam splitter is located at the upstream of the receiver, the transceiving lens is located at the upstream of the beam splitter, and the scanner is located at the upstream of the transceiving lens; the extinction module comprises a first extinction device located at the emitting end of the emitter, a second extinction device located at the receiving end of the receiver and a third extinction device located between the transceiving lens and the scanner. The detection light and the echo light share the transmitting-receiving lens, so that the size and the manufacturing cost of the laser radar can be reduced; by arranging the extinction devices at multiple parts in the laser radar, stray light of each part can be eliminated in a targeted manner, and the detection precision of the laser radar is improved.
本申请实施例公开了一种激光雷达、自动驾驶系统及可移动设备,激光雷达,包括发射器、接收器、分束器、收发镜头、扫描器及消光模块,沿探测光的传输路径,分束器位于发射器的下游,收发镜头位于分束器的下游,扫描器位于收发镜头的下游;沿回波光的传输路径,分束器位于接收器的上游,收发镜头位于分束器的上游,扫描器位于收发镜头的上游;消光模块包括位于发射器的出射端的第一消光器、位于接收器的接收端的第二消光器及位于收发镜头与扫描器之间的第三消光器。本申请中探测光及回波光共用收发镜头,能够降低激光雷达的尺寸及制造成本;通过在激光雷达内的多个部位设置消光器,可以针对性的消除各部位的杂散光,提升激光雷达的探测精度。
