摘要：
A foreign substance detection system includes an optical device having an input surface through which is part of light emitted from a light source enters the optical device and a transparent face, provided in close contact with an inner surface of a glass, to transmit a light reflected from an area where a substance is not present on an outer surface of the glass toward a first light-receiving member; a light-guiding member to guide another part of the light that does not pass through the input surface, the guided light being to be reflected from an area where a substance is present on an inner surface of the glass toward a second light-receiving member; and an foreign substance detection processor to detect an outer substance based on the first light-receiving member and detect the inner substance based on the second light-receiving member.
