摘要： 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.

摘要： 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.

摘要： A laser scanner includes: a light source; a scanning mirror that scans laser light emitted from the light source, toward a target object by oscillating about axis C; a photodetector that generates a photodetection signal upon receiving the laser light reflected from the target object; a controller that controls emission of the laser light by the light source, and that performs sampling on the photodetection signal; and a detector that detects an amount of displacement of the scanning mirror, and calculates a resonant frequency of the scanning mirror based on the amount of displacement detected. The controller determines a time at which the laser light is emitted from the light source and a time at which sampling is performed on the photodetection signal, based on the resonant frequency calculated.
