hemispherical reflectance

基本解释

This sphere serves as a diffuse light source, which enables measurements of the hemispherical reflectance, or the directional absorptance, respectively.
这个球作为扩散光源，使测量的半球形或定向吸收率的反射系数，分别使用。
The directional emissivity is deduced from the Bidirectional Reflectance Distribution Function(BRDF)in the hemispherical scattering space of the objects.
利用双向反射分布函数测量系统，通过对物体表面双向反射分布的测量来获得其方向发射率。
Reveals the importance of differentiating bidirectional reflectance factor ( BRF ) from hemispherical reflectance factor and shows the errors caused by the confusion.
本文通过分析，说明了区分双向反射因子和半球反射因子概念的重要性以及误用它们所会造成的误差。
