Abstract: A sensor pod configured to be mounted to a vehicle. The sensor pod including: a housing; a sensor mounted to the housing, the sensor oriented such that when the sensor pod is mounted to the vehicle the sensor faces an area rearward of the sensor pod; and an airflow deflector mounted to the housing adjacent to an exterior surface of the sensor, the airflow deflector including a body spaced apart from the housing, the body defining a first airflow passageway through an interior of the body and a second airflow passageway between the body and the housing. The airflow deflector is configured to direct a first layer of airflow through the first airflow passageway such that the first layer of airflow flows generally parallel to the exterior surface of the sensor, and direct a second layer of airflow through the second airflow passageway towards the exterior surface of the sensor.
