Abstract:
An optical device includes a light-emitting unit and a light-receiving unit. The light-emitting unit emits light forward in a first direction. The light-emitting unit has a light-emitting-side through hole that causes light traveling backward in the first direction to pass through. The light-receiving unit is arranged backward in the first direction relative to the light-emitting unit. The light-receiving unit has a light receiver that receives light after the light has passed through the light-emitting-side through hole.
