Abstract
A laser rangefinder includes a light source, a scanning mirror that scans laser light emitted from the light source by oscillating about an axis of oscillation J extending in a predetermined direction, a first lens that is disposed on an optical path of reflected light from a target object and condenses the reflected light onto the scanning mirror, a second lens that is disposed on an optical path of and condenses reflected light from the scanning mirror, and a photodetector that receives the reflected light condensed by the second lens. The first lens and the second lens are disposed in positions other than positions on an optical path of the laser light between a point of emission from the light source and a point of exit from the laser rangefinder.
