【摘要】 介绍了光源偏振度的测量和消偏振的方法以及照度计偏振误差的概念。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。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。更多还原

【Abstract】 The measurement method of the polarization grade for the source and depolarization and the concept of the polarization error for the illuminance meter are described. The polarization grade of three lamps for the laboratory and the polarization error of two illuminance meters are measured. The measuring results evince the polarization grade of the source is 10% at most, and the meters are not polarization sensitive to normal incidence.更多还原
