On the basis of polar ized detect ion mechanism, the space characteristics of the polarized reflect ion spectrum and the variation law of the polar ized Dvalue curve const ituted by the vertical vibration component and parallel vibration component of the reflected light are discussed. As a result, the Dvalue of vibration component and parallel vibration com ponent of the ref lected light vary w ith the reflective index , and the values reach the maximum at the light s incidence angle is about 80. Along w ith the in crease of the reflective index , the value of R gradually increases, and along w ith the incidence angle increases from 0 to 90, the value of R firstly increases and t hen decreases. Com pared the information of polarized Dvalue spec
