Claim 0:
1. A LiDAR, comprising:
an emission apparatus, configured to emit a detection laser beam;
a scanning apparatus, configured to receive the detection laser beam and emit the detection laser beam to a detection field of view, and to receive an echo laser beam and deflect the echo laser beam to a receiving apparatus; and
the receiving apparatus, configured to receive the echo laser beam,
wherein the scanning apparatus comprises a rotating mirror, the rotating mirror comprises multiple scanning surfaces, and divergence angles of at least two adjacent scanning surfaces in the multiple scanning surfaces corresponding to a center of the rotating mirror are unequal; and
wherein the LiDAR comprises a total detection field of view and a target detection field of view, the rotating mirror comprises an adjacent first scanning surface and second scanning surface,
a divergence angle of the first scanning surface corresponding to the center of the rotating mirror is equal to a sum of half of an angle of view of the total detection field of view and a set first redundant angle; and
a divergence angle of the second scanning surface corresponding to the center of the rotating mirror is equal to a sum of half of an angle of view of the target detection field of view and a set second redundant angle.
