1. A light reflection device comprising:
a first reflector configured to reflect an optical signal emitted from a light output unit to an object;
a second reflector configured to reflect the optical signal reflected from the object to a light receiving unit;
a blocking plate interposed between the first reflector and the second reflector;
a motor configured to rotate at least one of the first reflector, the second reflector, and the blocking plate; and
a coupling part configured to couple the first reflector, the second reflector, and the blocking plate so that the first reflector, the second reflector, and the blocking plate rotate at the same angle on the basis of a rotation axis,
wherein the blocking plate includes a first surface and a second surface, which are opposite sides of the blocking plate,
the first reflector is located on the first surface of the blocking plate, and
the second reflector is located on the second surface of the blocking plate, and
wherein the coupling part passes through the first reflector, the second reflector, and the blocking plate.
