多波长激光角分辨散射测量系统

Measurement System of Angle-resolved Scattering under Multiwavelength Illumination

本文介绍所研制的微机控制的激光角分辨散射自动测量系统，讨论了该测量系统的动态范围、校准、线性度和重复性．同时给出了多波长照射下，聚四氯乙烯（Ｆ４）粉末压制的漫反射标准板的角分辨散射分布特性和偏振特性的实验结果．

In this papers the principle and automatic measurement system of angleresolved scattering are described. The dynamoic range, sensitivity and reproductively are discussed. The angle-resolved scattering distribution and polarization properties of polytetrafluoroethylene diffuse reflectance plate are measured under rnultiwavelength laser illumination in order to test the system function and properties.
