An inspection system includes a source for emitting a light beam, a sensor for capturing images of a target area, and an optical system for splitting the light beam into a plurality of paths for illuminating the target area. One embodiment of the firelog pan includes a base, risers in the base that permit airflow under a firelog placed on the risers, and sidewalls that retain ash from a firelog burned in the firelog pan. The calculating unit calculates the position of the moving object relative to the host vehicle on the basis of displacement angles and of the representative point A with respect to the optical axis on an assumption that the representative point A is on a plane including a surface with which the host vehicle is in contact. The second surface of the first semiconductor chip and the first surface of the other semiconductor chip are interconnected by a lead frame with an A.
