Abstract
A distance measuring device includes: a modulated light output unit configured to output a modulated light; a transmitting scanner configured to emit an input light, which is one branched light of the modulated light, as an emitted light; a receiving scanner into which the emitted light reflected by a target object is incident as an incident light, the receiving scanner outputting the incident light as a reflected light; and a measuring unit configured to measure a distance to the target object by combining the reflected light and a reference light which is the other branched light of the modulated light. The modulated light output unit outputs at least two modulated lights having modulation frequencies different from each other by chirping the modulation frequencies to approach each other.
