波片相位延迟量误差、快轴角度误差和检偏器透光轴角度误差是影响基于旋转波片法的偏振检测装置测量精度的主要因素。通过对波片和检偏器参数进行校准，可有效提高检测装置测量精度。针对现有校准方法操作复杂的不足，提出一种偏振检测装置器件参数校准新方法。该方法以水平线偏振光[1,1,0,0]T作为标准参考光，分别在检偏器方位角为0°和45°时，对标准参考光各进行一次测量，计算得出器件参数误差，从而实现偏振检测装置器件参数校准。实验结果表明，通过器件参数校准，偏振检测装置测量误差由原来的3%降低至0.87%以内。

The retardation error, the fast axis angle error of wave-plate and the angle error of polarizer are the main error sources of polarimeter based on rotating quarter-wave method. The measurement accuracy can be effectively improved by calibrating the polarimeter. A new simple calibration method of polarimeter is proposed. Horizontal linearly polarized light [1,1,0,0]T is used as a standard reference light, and it is measured when the polarizer is fixed on 0° and 45° respectively. The parameter errors of device can be calculated and obtained to calibrate the polarimeter. The experimental results show that the measurement error is reduced by the proposed method from 3% to less than 0.87%.
