| 摘 要： | 目前的商用偏振分析仪检测速率较低，因此在检测光纤通信中高速信号的偏振态时，需要自行搭建测量系统并结合高速实时数字示波器使用.此时，系统定标就显得尤为重要，定标方法也将直接影响测量的准确性.针对光纤型高速偏振态检测系统提出了定标方法，先通过Mueller矩阵算法对其进行了理论分析，进而通过实验证明了该定标方法准确可行，测量误差水平小于±3%.

| Abstract: | Due to the relatively low sampling rate of current commercial polarization state analyzers,a specialized measurement system will need to be built with the use of high-speed real-time digital oscilloscopes if the detection of polarization state for a high-speed signal is required.At this point,the system calibration becomes particularly important,and the calibration method will directly decide the measurement accuracy.A calibration method is proposed for an optical fiber high-speed polarization state detection system.This method is theoretically analyzed by Mueller matrix,and then it is proved that the calibration method is feasible and accurate,of which the measurement error is less than ±3%. |
