  "textContent": "A ranging method and a range finder allow reliable measurement of the distance to a target object even when the target obj ect has a very low reflectivity and/or under conditions with disturbances. The range finder includes: a light receiving element configured to receive a reflected component of light emitted to a target object; a first detection unit and a second detection unit configured to perform two different types of detections with different detection gains; and a distance/light-intensity calculation processing unit serves as a calculation unit for calculating a measured distance based on a combination of result patterns of the detections performed by the first and second detection units. The range finder determines a distance by causing each of the first and second detection units performs at least two detections with a time interval per a single light emission.",
