磁光玻璃费尔德常数的波长依赖性和磁光玻璃光纤电流传感器中存在的问题

Wavelength-dependence of Verdet Constant of Magneto-optic Glass and Corresponding Problems in Magneto-optic Glass Fiber Current Sensor

介绍了磁光玻璃的费尔德常数与工作波长的关系。对ZF1、ZF6磁光玻璃样品,测试了不同工作波长下的费尔德常数。实验值和理论值基本一致,并指出了误差来源。最后,分析了磁光玻璃应用在磁光玻璃光纤电流传感器中存在的问题。

In this paper we introduce the relationship between Verdet constant of magneto-optic glass and operating wavelength theoretically and experiment on ZF1 and ZF6 magneto-optic glass samples. The experimental results are in agreement with the theory. We also analyze the sources of errors. At the last section of this paper we discuss the corresponding problems in magneto-optic glass fiber current sensor.
