Lidar apparatus and lidar system comprising the same

A lidar system, comprising:

• an installation object;
• a laser generating source fixed on the installation object to generate a laser;
• a first fixture fixedly disposed on the installation object;
• a first rotating body disposed to rotate about a rotation axis with respect to the first fixture, and provided with a first laser transmitting module for transmitting a laser generated by the laser generating source to the outside and a first laser receiving module for receiving a laser reflected from an external object;
• and
• a first light guide unit disposed on the rotation axis to transmit a laser generated by the laser generating source from the first fixture to the first 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.
