LIDAR device

A LIDAR device, comprising:

• a light transmitting unit for transmitting laser light;
• a light receiving unit for receiving the laser light received by being reflected from the outside;
• a scanner comprising a transmitting mirror unit that has a reflective surface for reflecting the laser light transmitted from the light transmitting unit and transmitting the same to the outside, and a receiving mirror unit that has a reflective surface for reflecting the laser light reflected from the outside and transmitting the same to the light receiving unit;
• and
• an optical path dividing unit disposed in the vicinity of the scanner so as to block, from flowing into the light receiving unit, scattered light of a propagating laser light reflected from the transmitting mirror unit,
• wherein in the scanner, the transmitting mirror unit comprises a first transmitting mirror unit and a second transmitting mirror unit which is disposed below the first transmitting mirror unit, and the receiving mirror unit comprises a first receiving mirror unit which is disposed between the first transmitting mirror unit and the second transmitting mirror unit, and a second receiving mirror unit which is disposed between the first receiving mirror unit and the second transmitting mirror unit, and
• wherein the optical path dividing unit comprises a plate-shaped first blocking member which is horizontally disposed at a boundary between the first transmitting mirror unit and the first receiving mirror unit, and a plate-shaped second blocking member which is horizontally disposed at a boundary between the second transmitting mirror unit and the second receiving mirror unit.
