Abstract
Provided is an apparatus for measuring distances in two directions. The apparatus in accordance with an embodiment of the present invention may include a sensor module configured to include a light emission unit configured to emit a first wavelength beam and a second wavelength beam, a light reception unit configured to receive reflected light emitted by the light emission unit and reflected from an object and first and second beam splitters respectively disposed ahead of the light emission unit and the light reception unit and configured to transmit the first wavelength beam and reflect the second wavelength beam; and a motor configured to rotate the sensor module. Accordingly, there is an advantage in that a production cost can be reduced because distance measurement and height measurement are performed using a single module.
