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: Disclosed are a light detection and ranging (LIDAR) for both short range and long range based on a single light source, and a vehicle including the same. The lidar includes: a transmitter configured to generate and transmit light; a first receiver configured to receive light reflected from an object within a first detection region of a short range; and a second receiver configured to receive light reflected from an object within a second detection region of a long range, wherein a two-dimensional region of the second detection region at least partially overlapping the first detection region is included in the first detection region.
