Abstract:
An optical distance measurement device includes: a photodetector including PDs for receiving interference light output from an optical interference unit and outputting detection signals of the interference light; and a switch for selecting one of the detection signals output from the PDs, in which a distance calculation unit calculates a distance to a measurement object on the basis of the detection signal selected by the switch.
