Lidar sensing device

A Light Detection and Ranging (LiDAR) sensing device, comprising:

• a sensing light source configured to radiate sensing light;
• a light transmitting reflector configured to reflect the sensing light radiated from the sensing light source;
• a scanner configured to reflect the sensing light reflected from the light transmitting reflector into a target, and to reflect incident light reflected from the target;
• a light receiving lens configured to pass the incident light reflected from the scanner;
• a light receiving reflector configured to reflect the incident light passing through the light receiving lens;
• and
• an optical detector into which the incident light reflected from the light receiving reflector is incident,
• wherein the light transmitting reflector is disposed such that a blockage area having a size corresponding to a size of the light transmitting reflector is formed in the incident light detected by the optical detector.
