Abstract

A detection device includes: a light source that emits, toward an object, light of a first wavelength band, and light of a second wavelength band that is less readily absorbed by water than the light of the first wavelength band; a polarization splitter that splits at least one of S-polarized light and P-polarized light from light that has been reflected or scattered at the object; a photoreceptor that receives light reflected or scattered at the object via the polarization splitter; and a control unit that determines a state of the object from information based on light received by the photoreceptor. The light emitted by the light source is random polarized light where the ratio of P-polarized light and S-polarized light is generally uniform.
