新型磁光调制器

A Novel Magneto Optic Modulator

介绍一种新型结构的磁光调制器。这种磁光调制器的显著优点是减小了磁光材料的温升, 从而减小了因温度效应引起的测量偏移。偏振角测量的实验表明, 其分辨力可达3.3×10- 7rad, 长期稳定性偏差为1.7×10- 6

A novel magneto optical modulator is presented. This kind of modulator can effectively reduce the temperature rise and thus reduce the magneto optical drift. Its performance is demonstrated in the polarization test, and the measuring resolution of 3.3×10 -7 rad and the long term stability error of 1.7×10 -6 rad are achieved.
