| 摘 要： | 利用1/4波片及偏光棱镜,设计了光强连续可调的圆偏振光衰减器,通过该器件可获得偏振度高且光强连续可调的圆偏振光.该衰减器解决了632.8 nm多膜氦氖激光器出射光为非完全自然光且偏振面随时间做随机变化导致实验误差的问题,为偏光信息测试系统提供了相对稳定的激光光源.

| Abstract: | A new kind of circularly polarized light attenuator is designed using the quarter-wave plate and the polarizing prisms.The attenuator can get high-degree circularly polarized light whose intensity could be adjusted continuously.This attenuator helps to eliminate experimental errors caused by 623.8 nm multimode He-Ne laser's non-complete natural light and changing random of polarization plane with time,and thus provides relatively stable laser light source for polarized light information testing system. |
