半阴偏振镜研究

The study of half-shade polarization prisms

半阴偏振镜是精确确定和测量平面偏振光的偏振方位的重要器件。本文做了系统的理论分析,并对所设计制作的半阴偏振镜进行了测试,结果表明,调整精度达到设计要求。

The half-shade Polarization prism is an important de- vice for determining and measuring accurately the azimuth of a beam of Plane Polarized light. In this paper, the theoretic analysis of the device was given systematically. Experimental test of the half-shade Polarization prism was made. The results show that the setting pre- cision agrees well with the theoretic design.
