<p>An object detection device includes: a light deflector that scans a scanning area with light emitted from a light source; and a light-receiving unit that, when an object is present in the scanning area, receives reflected light from the object through an imaging forming optical system. The light emitted from the light source irradiates an area having a shape longer in a second direction orthogonal to a first direction than in the first direction. Wpds/Wpdm<Wes/Wem is satisfied, where Wpdm is a length of the light-receiving region in the first direction, Wpds is a length of the light-receiving region in the second direction, Wem is a length of the area irradiated with the light emitted to the object, in the first direction, and Wes is a length of the area irradiated with the light emitted to the object, in the second direction.</p> |
