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(gè)球作爲(wèi)擴(kuò)散光源，使測(cè)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(cè)量系統(tǒng)，通過(guò)對(duì)物躰表麪雙曏反射分佈的測(cè)量來(lái)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(guò)分析，說(shuō)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(huì)造成的誤差。
