LASER SCANNER

摘要

A laser scanner includes a light source 4, a scanning mirror 6, and a first photodetector 12. The scanning mirror 6 includes: a first reflective surface 26 reflects the laser light from the light source 4; and a second reflective surface 30 that reflects, toward the photodetector 12, the laser light reflected from the target object 20. The first reflective surface 26 and at least part of the second reflective surface 30 are disposed at mutually different angles. When a first optical axis passing through the target object 20 and the first reflective surface 26 is parallel with a second optical axis passing through the target object 20 and the second reflective surface 30, a third optical axis passing through the first reflective surface 26 and the light source 4 and a fourth optical axis passing through the second reflective surface 30 and the photodetector 12 are at a predetermined angle relative to one another.
