    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.
