1. A lidar apparatus, comprising:
a laser generating source for generating a laser;
a fixture fixedly disposed on an installation object;
a rotating body disposed to rotate about a rotation axis with respect to the fixture, and provided with a laser transmitting module for transmitting a laser generated by the laser generating source to the outside and a laser receiving module for receiving a laser reflected from an external object; and
a light guide unit disposed on the rotation axis to transmit a laser generated by the laser generating source from the fixture to the rotating body
wherein a first optical fiber for transmitting a laser generated by the laser generating source towards the light guide unit is disposed in the fixture,
wherein a second optical fiber for transmitting a laser passing through the light guide unit towards the laser transmitting module is disposed in the rotating body, and
wherein the light guide unit guides a laser output from the first optical fiber to an input of the second optical fiber.
