Abstract: A laser radar includes a light source, a scanning mirror, a detector, and a reflector group. The scanning mirror includes an emitting reflective surface and a receiving reflective surface. The reflector group includes a first reflector and a second reflector. An included angle between the first reflector and the second reflector is a first included angle, an included angle between an incident laser beam of the emitting reflective surface and an emergent laser beam of the receiving reflective surface is a second included angle, and the second included angle is twice the first included angle. The emitting reflective surface is configured to reflect the laser beam emitted by the light source. The receiving reflective surface is configured to reflect, to the detector, the laser beam reflected back by an object. The reflect group is configured to change a propagation direction of the laser beam.
