摘要
阐述了双向反射分布函数(BRDF)的定义及其测量装置的工作原理,使用紧凑型BRDF测量装置分别对空间相机常用结构材料铝合金在不同加工和表面处理工艺下的表面散射特性进行了测量和对比分析。分析了测量装置可能存在的各种误差源并采取了相应的控制措施。通过对不同加工工艺和表面处理工艺下铝合金样块BRDF测量数据的对比,为后期空间相机方案设计时加工工艺的选取提供了参考。
The definition of bidirectional reflectance distribution function （BRDF） and the principle of measurment apparatus are expounded. Aluminum alloy materials are widely used in space camera. The BRDF data of aluminum alloy samples dealt with different processing technologies are scaled by the compact BRDF measurement system. Every error source of compact BRDF measurement system is analyzed, and the methods to control and correct these errors are proposed. Comparison among BRDF data of aluminum alloy samples dealt with different processing technologies is significative for the conceptual design of space camera.
