摘　　要：基于双向反射分布函数实验装置设计了验证布儒斯特定律的教学实验.通过测量介质反射面的反射光偏振态,可得到p偏振光消光时的入射角,即布儒斯特角,从而计算出该介质反射面的折射率.利用金属反射面和介质反射面的折射率差异,通过测量反射光的圆偏振分量,辨别金属/介质反射面.同时,通过测量金属反射面的反射光偏振态,可得到圆偏振分量最大时的入射角,即金属反射面的伪布儒斯特角.A teaching experiment for verifying Brewster law was designed based on the experimental device about the bidirectional reflectance distribution function.The incident angle of p-polarized light,known as the Brewster angle,could be obtained by measuring the polarization of the reflected light on the dielectric reflecting surface.Then the refractive index of the medium’s reflecting surface could be figured out.Furthermore,by exploiting the difference between the metallic reflecting and dielectric reflecting surface in refractive index properties,the metallic/dielectric reflecting surfaces could be distinguished by measuring the circular polarization component of the reflected light.Additionally,the incident angle could be gotten in the case of the maximal circular polarization component by measuring the polarization state on the metallic reflecting surface,that was just the pseudo-Brewster angle of the metallic reflecting surface.
