Abstract
A distance measurement device for measuring a distance to an object that exists in a distance measurement region includes: a light source configured to emit laser light; a lens configured to converge the laser light emitted from the light source, into substantially parallel light; a tubular light blocking member disposed on an optical path of the laser light emitted from the light source and surrounding the optical path; a photodetector configured to detect reflected light, of the laser light, reflected at the distance measurement region; and a condensing lens configured to condense the reflected light passing through the outside of the light blocking member, onto the photodetector.
