The invention provides a laser radar device. The laser radar device specifically comprises a laser emission module and an optical scanning module. The laser emission module comprises a laser and an emission optical unit, the laser is used for emitting laser to the emission optical unit, and the emission optical unit is used for dividing the laser into multiple split light beams; the optical scanning module comprises a rotating mirror unit and a motor unit integrated in the rotating mirror unit, the motor unit is used for driving the rotating mirror unit to rotate, the rotating mirror unit comprises a rotating shaft and a plurality of reflecting mirror surfaces, and the angles of the reflecting mirror surfaces relative to the rotating shaft are different; and the target line number of the laser radar device is determined through the number of the split light beams and the number of the reflecting mirror surfaces. According to the laser radar device, through the combination of the transmitting optical unit and
