Abstract
An optical detector includes a light emitter having a light emitting window extended in an extension direction to emit a projection beam from the light emitting window toward a measurement area and to detect a return beam from the measurement area. The optical detector includes a scanning mirror that scans by reflecting the projection beam. The scanning mirror swings within a finite angular range around a rotation axis that is along a direction corresponding to the extension direction.
