沟道光谱偏振法测量光偏振态的光谱相关性。这项技术以其快照特性为标志，因为可以从单个强度谱同时确定完整的偏振态。然而，在没有隔热的情况下，它对温度高度敏感，这反过来又降低了极化重建的精度。在本文中，我们提出了一种基于光纤的通道光谱偏振仪的校准技术，该技术利用相移干涉法来精确解调延迟器的相位，从而提高了获取的斯托克斯参数的精度。此外，它还实现了对环境扰动不敏感的强健的光谱偏振性能。实验结果表明，与参考光束定标法相比，相移干涉定标法使斯托克斯重建结果提高了近3倍。
Channeled spectropolarimetry measures the spectral dependence of the polarization states of light. This technique is marked by its snapshot feature, in that the complete polarization states can be determined simultaneously from a single intensity spectrum. However, without athermalization, it suffers from high sensitivity to temperature, which in turn, degrades the polarimetric reconstruction accuracy. In this paper, we present a calibration technique for a fiber-based channeled spectropolarimetry that leverages phase-shifting interferometry to accurately demodulate the retarders' phase, thereby improving the accuracy of the acquired Stokes parameters. Additionally, it enables robust spectropolarimetric performance that is insensitive to environmental perturbations. Experimental results demonstrate that calibrations using phase-shifting interferometry improve the Stokes reconstruction results by approximately a factor of 3 when compared to the reference beam calibration method.
