实验测量了硅太阳能电池板在380~780 nm内的光谱双向反射分布函数(BRDF)，分析了光谱双向反射分布函数随波长及散射角的变化趋势，将色度学理论和光散射理论相结合，寻找到光散射理论中的双向反射系数与色度学中光谱反射率因数的联系，进而获得了一种通过光谱BRDF测量实现物体色度特性表征的方法。并且采用CIELAB均匀色空间中的明度指数和色品指数、定量地描述了几种入射条件下、不同散射方向上目标样片的颜色特性。将目标样片的光谱双向反射分布函数的研究应用到颜色光学领域中，对目标的探测、识别和颜色复现等具有重要的应用价值。

The spectral bidirectional reflectance distribution function (spectral BRDF) of silicon solar cell panel was measured in the visible spectrum (380-780 nm). The variation of spectral BRDF with wavelength and scattering angle was analyzed. The relationship between the bidirectional reflectance factor in the theory of light scattering and the spectral reflectance factor of colorimetry was obtained by combining the theories of colorimetry and light scattering, a method was developed for characterizing chromaticity characteristics of object using the spectral BRDF. Using the lightness index and chromatic indexes and in CIELAB color system, chromaticity characteristics of target samples was described under the condition of several incident and scattering directions. The application of spectral BRDF of target samples in color optics possesses important values in the detection, identification and color reproduction of target samples.
