Beschreibung
Zusammenfassung:	An optical ranging device installed in a vehicle includes: a light emitter that emits irradiation light; a scanner that scans a predefined scan region with the irradiation light; a light receiver that, in response to the scan with the irradiation light, receives light including reflected light of the irradiation light from the scan region and outputs an electrical signal corresponding to the reception state of the reflected light; and a measurer that measures the distance to an object within at least the scan region based on the signal output from the light receiver. The optical ranging device changes the state of scanning by the scanner with the irradiation light in accordance with the traveling situation of the vehicle.
