摘 要：
In optical sensor, light emission system is by the radiant light of the linear polarization on the first polarization direction from the inclined incident
direction in normal to a surface direction about the target object with paper shape to the surface emitting. First optical detection system includes the first
photodetector arranged in the first optical path of specular light, and the specular light emits from light emission system and from target object mirror-reflection.
Second optical detection system includes the second photodetector arranged in irreflexive the second optical path to diffuse of the plane of incidence from
