<p>PROBLEM TO BE SOLVED: To provide a distance measurement device capable of reducing an error due to the atmospheric environment.SOLUTION: Provided is a distance measurement device comprising: a first wavelength sweeping light source for emitting a first light the wavelength of which changes in a first wavelength range; a second wavelength sweeping light source for emitting a second light the wavelength of which changes in a second wavelength range differing from the first wavelength range; a radiation unit for radiating the first and the second light; a light-receiving unit for receiving a first reflected light of the first light radiated by the radiation unit and a second reflected light of the second light radiated by the radiation unit; and a control unit for deriving a distance from the radiation unit to where the reflection occurred on the basis of the first and the second light received by the light-receiving unit.</p> |
