中文摘要:
      为解决角锥棱镜失偏效应,提出一种外加晶片的椭圆偏振光纠偏方案。总结角锥实棱倾斜时的修正公式,同时建立角锥在顺、逆时针反射次序下的纠偏模型。分析该模型表明利用两个半波片和一个延迟片可以使角锥的入/出射偏振态保持不变。根据上述模型,用1 064 nm波长的激光器,对实棱线竖直摆放的BK7玻璃角锥进行顺、逆时针纠偏实验。光波矢与水平方向的夹角在90°至0°之间变化,以获得不同的线偏振态,经纠偏后最大失偏椭圆率绝对值从35°纠正为5°。对于近圆偏振光,经纠偏后椭圆率从44°下降到40°。
英文摘要:
      In order to solve the depolarization effect of the corner cube, an elliptically polarized light correction scheme with the external wave plates is proposed. The modified formula of the corner cube with a tilted solid ridgeline is summarized, and a polarized light correction model with clockwise and counter-clockwise reflection paths is established. The analysis of the model shows that two half-wave plates and one retarder can keep the polarization state of the incident ray equal to that of the emerging ray. Based on the model, by using a 1 064 nm laser, the correction experiment on the BK7 glass corner cube whose solid ridgeline is placed vertically in clockwise and counter-clockwise reflection paths is carried out. When the angle between the polarized direction and the horizontal direction of the linearly polarized incident light varies from 90° to 0°, the maximum absolute value of the ellipticity of the light in depolarization is corrected from 35° to 5°. When the incident light is with the approximately circular polarization, its ellipticity drops from 44° to 40° after correction.
