The polarization grade of three lamps for the laboratory and the polarization error of two illuminance meters are measured 测量了实验室用的三支灯的偏振度及两台照度计的偏振误差。
The relationship between the thermal emission polarization and viewing angles in metal targets is studied by using this thermal imaging polarimeter 利用该系统,研究了金属板热红外偏振度和观测角之间的关系。
The polarization degree of metal plate surface increases with the viewing angle , when the viewing angle is larger than 20 degree 在观测角大于20时,随着观测角度的增大,金属目标板热红外偏振度的数值也增大。
The measuring results evince the polarization grade of the source is 10 % at most , and the meters are not polarization sensitive to normal incidence 测量结果表明,光源偏振度均小于10 % ,当光垂直入射时对照度计的影响是非常小的。
Using the degree of depolarization , cause of depolarization was discussed , and the droplet can be viewed as a sphericity in the lighter fog 由退偏振度随雾浓度的变化讨论了退偏产生的原因,指出雾浓度较低时,雾滴可近似视为球形。
