基于差分检测的球形碱金属气室导致线偏光转角的测量
|
摘要
对球形碱金属气室导致的线偏光振动方向转角进行了理论研究与差分检测实验测量。结果表明,当光束通过中心位置、入射面与振动方向相垂直或平行的位置时,气室对其偏振态没有影响,而其他位置均会产生一定偏转角,且偏转角随位置的不同而变化。对直径12mm、壁厚0.9mm的气室,偏离中心0.7 mm处产生的理论偏转角约为0.08°。在使用球形碱金属气室作为中心元件的仪器时,需要考虑其对线偏光转角的明显影响。
Rotation of the linearly polarized light caused by spherical alkali vapor cell is studied theoretically and measured experimentally.The results show that the vapor cell has no effect on the polarization state of linearly polarized light when the light beams pass through the cell center,and the incident plane is parallel or perpendicular to the polarization orientation.While the other positions will produce a certain rotation,and the rotation angle varies with the positions.For the ideal vapor cell with the external diameter of 12 mm and thickness of 0.9 mm,the theoretical rotation is up to 0.08°when a position is off center of 0.7 mm.Therefore,the effect of polarization rotation should be considered,when using the spherical alkali vapor cell as a central element of the instrument.
