Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 17:
18. The distance measurement device according to claim 15, wherein
the controller instructs the light source section to emit, in addition to the first light pulse, a second light pulse that follows the first light pulse,
the photodiode causes the signal charge to be generated by receiving a second reflected light pulse corresponding to the second light pulse,
the signal edge detector performs a second detection operation of detecting a second signal edge corresponding to the second reflected light pulse in the light reception signal, and
the time measurement section performs, on a basis of the second signal edge, a second measurement operation of measuring a second time interval from an emission timing of the second light pulse in the light source section to a reception timing of the second reflected light pulse in the light receiver.
