Abstract: One aspect is a scanning light detection and ranging (LiDAR) having an optical structure which shares a transmitting and receiving lens. In one embodiment, the LiDAR includes a hole mirror disposed to have a first angle with respect to a horizontal surface and including a hole and a reflecting surface and a beam source configured to output a pulsed laser beam from one side of the hole mirror toward the hole. The LiDAR also includes a transmitting and receiving lens configured to generate a collimated beam to move the pulsed laser beam which passed through the hole toward a measurement target, receive a beam reflected from the measurement target, and transmit the reflected beam to the hole mirror. The LiDAR further includes a beam detector disposed to face the reflecting surface of the hole mirror and configured to receive the beam reflected from the hole mirror and convert the reflected beam into an electronic signal.
