Beschreibung
Zusammenfassung:	A LiDAR sensor includes an optical element and a light emitter aimed at the optical element. The optical element directs light from the light emitter into a field of illumination The LiDAR sensor includes a light detector having a field of view overlapping the field of illumination. An ultrasonic transmitter and ultrasonic receiver are on the optical element. A method of operating the LiDAR sensor includes controlling operation of the light emitter based on characteristics of the detected sound from the ultrasonic transmitter.
