| 摘 要： | 针对WXG-4型旋光仪的均匀亮视场和均匀暗视场的亮度对比不明显问题进行了研究,分析了三分视场光强与起偏器透振方向的关系,得出原因是起偏器透振方向与半波片的光轴夹角太大.旋转起偏器,使其透振方向与半波片的光轴夹角减小并固定,均匀亮视场和均匀暗视场的亮度对比明显,使仪器恢复正常使用. |

| Abstract: | To improve the brightness contrast between bright vision and dark vision in WXG-4 polarimeter,the relationship between visual field's light intensity and direction of polarization of the polarizer is analyzed.The reason is that the angle between the polarization direction and the optical axis of the half-wave plate is a little too large.The problem is solved by rotating the polarizer to decreasing the angle. |
| Keywords: | polarimeter polarizer optical activity |
