摘要
详细分析了晶体消光比和应力双折射相位差的关系,提出了用单1/4波片法测量晶体消光比,推导出了计算公式,并对不确定度进行了分析,给出了对比实验值,证明了该方法较目前常用的方法具有更小的测量不确定度。
Abstract
The relation of the crystal extinction ratio and stress-induced birefringence phase diffrence are analyzed in details. The method making use of a single 1/4 wave plate for measuring crystal extinction ratio is reported. The cumputational formula and testing results are given. The uncertainty is analyzed and it shows that the measuring uncertainty of this method is less than that of the method usually used.
