In this work, the error sources that affect a dual rotating retarder polarimeter working in a discrete rotation scheme are studied. Moreover, those errors not sufficiently analyzed in the literature are addressed in detail. To this end, the equations necessary for characterizing its components, performing its calibration, and carrying out measurements are deduced. We also discuss strategies to perform the experimental implementation, correct the existing errors, and estimate the margin of uncertainty associated with those errors that cannot be corrected. The study developed in this work allows us to generate a polarimeter with an error margin of 0.2%, almost an order of magnitude below recently reported values.
在这项工作中,研究了影响以离散旋转方案工作的双旋转延迟器旋光仪的误差源。此外,还详细讨论了文献中未充分分析的那些误差。为此,推导了表征其组件、进行校准和进行测量所需的方程。我们还讨论了进行实验实施、校正现有误差以及估计与那些无法校正的误差相关的不确定度范围的策略。这项工作中开展的研究使我们能够制造出误差幅度为0.2%的旋光仪,几乎比最近报道的值低一个数量级。
