摘　　要：偏振探测的重构矩阵校准影响着偏振态再现的准确性。针对基于超表面透镜的偏振探测系统的重构矩阵校准进行了详细的理论分析,对校准基准态的选取进行了讨论,提出采用条件数与等加权方差两个准则来选择校准基准态。通过对比仿真模拟和偏振探测还原实验,均证明了选取正八面体基准态进行校准能够得到更加精准的重构矩阵,且具备更好的抗噪声能力。The calibration of the reconstruction matrix for polarization detection affects the accuracy of the polarization state restoration. In this paper, a detailed theoretical analysis of the reconstruction matrix calibration problem of a polarization detection system based on metalens is carried out. The selection of the calibration reference state is discussed, and two criteria of condition number and equal weighted variance are used to select the calibration reference state. Through the comparison of simulation and polarization detection reduction experiments, it is proved that selecting a regular octahedron reference state for calibration can obtain a more accurate reconstruction matrix and have better anti-noise ability.
