【摘要】 介绍了双向反射分布函数(BRDF)的概念及其测量原理。研制了一套基于微机控制的BRDF测量系统,激光波长覆盖了可见光到红外线的0.6328μm,1.34μm,3.39μm和10.6μm波段。用该装置对金刚砂纸进行了正入射情况下的半球空间反射特性测量,结果显示它具有相对较好的朗漫特性。更多还原

【Abstract】 The concept and the measuring theory of BRDF (bi-directional reflectance distribution function ) were discussed . A set of system based on personal computer for BRDF measurement was developed , whose laser wavelengths cover 0.6328 μn, 1.34μm, 3.39μm and 10.6μm from visible to infrared . The experimental results of the hemispherical reflectance measurements on silicon carbide paper at normal incidence show better Larnbertian diffusion.更多还原
