The division-of-focal-plane (DoFP) polarimeter can quickly and effectively obtain the polarization information of light in real time, where Stokes parameter reconstruction is a critical issue. Many reconstruction methods have been proposed to address this; however, their performance tends to degrade in the presence of noise. Thus, it is significant to clarify the noise-induced error in Stokes parameter reconstruction. In this work, we investigate the link between the noise-introduced error and the reconstruction method and develop a simple and effective way to evaluate the noise robustness of reconstruction methods. Furthermore, a novel experimental scheme of noise measurement, to the best of our knowledge, is designed to verify the theory. Based on the criterion, our scheme guides the selection of reconstruction methods and further promotes the practical application of the DoFP technique.
焦平面分割（DoFP）偏振计能够快速、有效地实时获取光的偏振信息，其中斯托克斯参数重建是一个关键问题。人们已经提出了许多重建方法来解决这个问题；然而，在存在噪声的情况下，它们的性能往往会下降。因此，阐明斯托克斯参数重建中噪声引起的误差具有重要意义。在这项工作中，我们研究了噪声引入的误差与重建方法之间的联系，并开发了一种简单有效的方法来评估重建方法的噪声鲁棒性。此外，据我们所知，设计了一种新颖的噪声测量实验方案来验证该理论。基于该准则，我们的方案指导重建方法的选择，并进一步推动DoFP技术的实际应用。
