Abstract: A light radiating portion radiates light with wavelength ?1 having predetermined absorptivity for an object and light with wavelength ?2 having smaller absorptivity for the object than the wavelength ?1, to a target, so as to scan in 2-dimensional directions. A light receiving portion receives scattered lights reflected by the target based on light with wavelength ?1 and light with wavelength ?2. A measuring portion generates information used for detection of the object at the target, based on difference between the two scattered lights with wavelength ?1 and wavelength ?2 received by the light receiving portion. An output portion outputs whether or not the object is present at the target, by 2-dimensional area information, based on scanning by the light radiating portion and information generated by the measuring portion.
