Abstract: A light detection and ranging (LiDAR) optical system, according to one embodiment of the present invention, comprises: a first mirror which is disposed to make a predetermined first angle with a horizontal plane and has a first hollow; a light source for outputting a pulse laser from the lower portion of the first mirror; a second mirror which is disposed to make a predetermined second angle with the first mirror so that the pulse laser passes through the first hollow and travels to a measurement target; at least two path control mirrors which reflect the pulse laser so that the path of the pulse laser is formed on a reflective surface of the second mirror; a light receiving lens for receiving, from the lower portion of the first mirror, light which has been reflected through the first mirror.
