The polarization grade of three lamps for the laboratory and the polarization error of two illuminance meters are measured 測量了實驗室用的三支燈的偏振度及兩臺照度計的偏振誤差。
The relationship between the thermal emission polarization and viewing angles in metal targets is studied by using this thermal imaging polarimeter 利用該系統(tǒng),研究了金屬板熱紅外偏振度和觀測角之間的關(guān)系。
The polarization degree of metal plate surface increases with the viewing angle , when the viewing angle is larger than 20 degree 在觀測角大于20時,隨著觀測角度的增大,金屬目標(biāo)板熱紅外偏振度的數(shù)值也增大。
The measuring results evince the polarization grade of the source is 10 % at most , and the meters are not polarization sensitive to normal incidence 測量結(jié)果表明,光源偏振度均小于10 % ,當(dāng)光垂直入射時對照度計的影響是非常小的。
Using the degree of depolarization , cause of depolarization was discussed , and the droplet can be viewed as a sphericity in the lighter fog 由退偏振度隨霧濃度的變化討論了退偏產(chǎn)生的原因,指出霧濃度較低時,霧滴可近似視為球形。
