摘要
探讨一种用双向反射分布函数测定仪测量目标表面光散射的方法,运用该测量系统在特定激光波段(0.808μm)下对卫星上太阳能电池板进行了实验测量.根据样片的BRDF实验数据,将遗传模拟退火算法应用于目标表面BRDF统计模型的参数反演中,获取样片的BRDF模型参数.实验数据曲线表明,拟合后的实验数据与参与优化的实验数据吻合的很好,结果说明用这种方法分析目标的散射特性是可行的和有效的.
A method on measure of the light scattering of the objective surface is introduced with the definition of the bidirectional reflectance distribution function. Using this system, an experiment is made on the solar panels of the satellite under the particular laser band（λ= 0. 808μm）. According the BRDF ex- perimental data,the genetic simulated annealing algorithm on statistics model of the BRDF is carried. Experimental data＇s curve shows that the data fitting is fit well with the data participating. The result indicates that this analysis method is viable and feasible.
