摘要
An optical sensor includes an irradiation system emitting linearly polarized light of a first polarization direction toward a surface of an object from an incident direction inclined with respect to a normal to the surface; a first light detection system including a first light detector placed on a light path of light emitted from the irradiation system and specularly reflected by the object; and a second light detection system including a separation optical element placed on a light path of light diffusely reflected by the object, on a plane of incidence of the object, and extracting a linearly polarized light component of the first polarization direction included in the light diffusely reflected by the object, a second light detector receiving the linearly polarized light component of the first polarization direction extracted by the separation optical element and a third light detector receiving the light diffusely reflected by the object.
