偏振调制型导波光学传感器光路误差分析

Analysis of the Error of Polarizing Modulation Optical Transducer

对一种典型的用光学玻璃作探测头的光学电流传感器光路进行分析计算,探讨了影响测量的一些因素。分析计算和试验结果都表明光学玻璃探测头的面型加工误差引起的线性双折射及光学元件的装配误差对探测器灵敏度和测量精度都有直接的影响。

Analysis and calculation are given to a type of polarizing modulation glass ring optical current transducer. Some factors affecting the measurement are discussed. The calculation and experimentation show that the processing error of glass ring plane and the assembly error of optical element have a direct effect on the sensibility and the measuring precision of the detector (optical current transducer).
