摘要：An optical sensor is disclosed, including an irradiating system; a first

photodetecting system including a first photodetector which is arranged on an optical

path of a light which is specularly reflected from a subject; a second photodetectingsystem including an optical element which is arranged on an optical path of a light whichis diffuse reflected from the subject within an incident face in the subject and whichseparates a linearly polarized component in a second polarizing direction which isorthogonal to a first polarizing direction and a second photodetector which receives alight separated by the optical element; and a restricting member which is arranged on anoptical path of an incident light with respect to at least one of the first photodetectorand the second photodetector and which restricts a light receiving range in the at leastone photodetector.
