Abstract
A laser scanner includes a light source, a scanning mirror, and a first photodetector. The scanning mirror includes: a first reflective surface reflects the laser light from the light source; and a second reflective surface that reflects, toward the photodetector, the laser light reflected from the target object. The first reflective surface and at least part of the second reflective surface are disposed at mutually different angles. When a first optical axis passing through the target object and the first reflective surface is parallel with a second optical axis passing through the target object and the second reflective surface, a third optical axis passing through the first reflective surface and the light source and a fourth optical axis passing through the second reflective surface and the photodetector are at a predetermined angle relative to one another.
