Abstract: A ranging device includes a light emitting circuit configured to emit light and a splitter configured to split the light into multiple beams. The ranging device includes a scanning circuit configured to perform scanning in two axial directions while aiming the multiple beams toward an emission area. The ranging device includes multiple light receiving circuits configured to respectively receive beams obtained from the multiple beams that are reflected or scattered by an object existing in the emission area, the light receiving circuits being configured to respectively output light reception signals. The ranging device includes a distance-information outputting circuit configured to output distance information about the object, the distance information being obtained based on each of the light reception signals that is output from a corresponding light receiving circuit among the multiple light receiving circuits.

Abstract: A light scanning device includes a light emitter configured to emit light; an optical scanner configured to cause the light to scan; a light receiver configured to receive returning light as scanning light from the optical scanner being reflected or scattered on an object; and an optical scanning controller including processing circuitry configured to control the optical scanner. The optical scanner includes a rotating polyhedron configured to include a plurality of reflective surfaces, to cause the light to scan around a first axis by reflecting the light on a reflective surface while rotating around the first axis; a supporter configured to support the rotating polyhedron; and a rotating mechanism configured to rotate the supporter around a second axis that crosses the first axis, to cause the light reflected on the reflective surface to scan around the second axis.
