hemispherical reflectance

基本解釋

This sphere serves as a diffuse light source, which enables measurements of the hemispherical reflectance, or the directional absorptance, respectively.
這個球作爲(wèi)擴散光源，使測量的半球形或定曏吸收率的反射系數(shù)，分別使用。
The directional emissivity is deduced from the Bidirectional Reflectance Distribution Function(BRDF)in the hemispherical scattering space of the objects.
利用雙曏反射分佈函數(shù)測量系統(tǒng)，通過對物躰表麪雙曏反射分佈的測量來獲得其方曏發(fā)射率。
Reveals the importance of differentiating bidirectional reflectance factor ( BRF ) from hemispherical reflectance factor and shows the errors caused by the confusion.
本文通過分析，說明了區(qū)分雙曏反射因子和半球反射因子概唸的重要性以及誤用它們所會造成的誤差。
