|luminance temperature;[天物]亮度溫度
“brightness temperature”（亮度溫度）是一個物理學和遙感領域常用的術語，其含義及背景如下：
亮度溫度是指一個物體在特定波長或頻率下，其輻射的亮度所對應的等效黑體溫度。即使物體本身并非理想黑體，其輻射強度可通過黑體輻射公式轉換為溫度值，這一溫度即稱為亮度溫度。
亮度（brightness）
指物體表面的明暗程度或輻射強度，與光線的反射、發射特性相關。
溫度（temperature）
表示物體冷熱程度的物理量，此處特指通過輻射能量推算的溫度。
亮度溫度可通過普朗克輻射定律計算：
$$
B{
u}(T) = frac{2h
u}{c} frac{1}{e^{h
u/(kT)} - 1}
$$
其中，$B{
u}(T)$為輻射亮度，$T$為亮度溫度，$h$為普朗克常數，$k$為玻爾茲曼常數。
