【Abstract】 Angular distribution and depolarization properties of polytetrafluoroethylene diffuse reflectance plate were investigated under multiwavelength laser illumination with different beam divergences in this paper. Results indicate that this plate has a good diffuse reflectance and depolarization properties which can be used as a standard of diffuse reflectance.更多还原
