Abstract: Disclosed are a light receiving module and a light detection and ranging (LIDAR) including the same. The light receiving module according to one embodiment of the present disclosure includes a receiving lens configured to receive external light, a reflective mirror configured to selectively reflect some of the light received by the receiving lens, and a detector configured to detect the light reflected by the reflective mirror, wherein the reflective mirror includes a mirror body having a first surface on a side on which the light received by the receiving lens is incident and a second surface on an opposite side of the first surface, a reflective layer provided on the first surface to reflect light in a designed wavelength region selected according to a predetermined criterion among the light received by the receiving lens, and to transmit light in a noise wavelength region other than the designed wavelength region, and a transmissive layer provided on the second surface so that the light in the noise wavelength region that has passed through the mirror body is transmitted.

Abstract: The present invention relates to a light detection and ranging (LiDAR) system. The LiDAR system may include a transceiver configured to generate pieces of light having different wavelengths and receive pieces of reflected light having different wavelengths reflected from a target, a beam splitter configured to divide the pieces of light having the different wavelengths into long-wavelength light having a relatively long wavelength and short-wavelength light having a relatively short wavelength, and a scan mirror configured to transmit the long-wavelength light and the short-wavelength light, which are divided by the beam splitter, to an outside and allow reflected light of the long-wavelength light and reflected light of the short-wavelength light to be incident on the transceiver through the beam splitter.
