Abstract

The laser distance measuring device includes: a laser light emission unit for emitting laser light; a scanning mechanism for scanning the laser light by changing an output angle thereof; a light receiving unit for receiving reflected light of the laser light from an object, to thereby output a light reception signal; a light-detector control circuit for causing the light receiving unit to output the reception signal after setting a light receiving sensitivity for the reflected light at the time when the output angle is small, higher than a light receiving sensitivity for the reflected light at the time when the output angle is large; and a distance calculation unit for calculating, based on the reception signal, a distance to the object. This enhances the distance measuring capability in both cases of measuring a short distance and a long distance.
