Abstract
A distance measuring device applies laser light to a distance measurement region and measures a distance to an object that exists in the distance measurement region. The distance measuring device includes: a condensing lens configured to condense reflected light, of the laser light, reflected by the object; a tubular adjustment member disposed at a stage subsequent to the condensing lens and having a first reflecting surface and a second reflecting surface formed on an inner surface on which the reflected light condensed by the condensing lens is incident, a tilt angle of the second reflecting surface relative to an optical axis of the condensing lens being different from that of the first reflecting surface; and a photodetector configured to receive the reflected light that has traveled through the adjustment member.
