摘要
针对星载漫射板远紫外波段(140~240 nm)的双向反射分布函数测量过程中,探测器响应线性问题和紫外光源稳定性差的问题,提出一种采用光源监测比例补偿的相对测量方法.根据测量方法设计了一种基于六自由度转台结构形式的测量系统,该系统采用漫射板两维平移+两维转动、探测器两维转动的组合运动形式,可实现漫射板半球空间内任意点、任意方位的双向反射分布函数测量.用所提方法进行测量实验,并对影响系统测量结果的主要因素进了不确定度分析,结果表明总测量不确定度约为5.5%.
Abstract
In order to solve the problems of the linear response of the detector and the poor stability of the UV light source in the process of bidirectional reflectance distribution function bidirectional reflectance distribution function measurement of the far ultraviolet spectrum (140~240 nm) for solar diffuser, a relative method of measurement using the light source monitoring proportional compensation was proposed. According to the method, a system based on the structure of six-degree-free turntable was designed. The system can measure the bidirectional reflectance distribution function of the solar diffuser at any point and any position in the hemisphere space by controlling the diffuser with two-dimensional translation and rotation and the detector with two-dimensional rotation. The measurement experiment was carried out by using the proposed method, and the main factors that affect the measurement results of the system were analyzed. The total uncertainty of measurement is about 5.5%.
