摘要
采用马赫-曾德尔干涉仪对超磁致伸缩棒相位调制器的相移性能进行了实验测试,计算结果表明:在所测试范围内,平均相移系数为0.08621rad/(A/m)。同时,对影响相位调制器相移能力的几个因素进行了理论和实验分析,为研制新型光纤传感器做准备。
The performance of phase modulation employing giant magnetostrictive rod were tested by using a Mach-Zehnder type fiber interferometer, and it＇s result indicated that the average phase-shift coefficient in the range of 30-50 kA/m was 0.08612 rad/（A/m）. At the same time, some causal aspects which influenced it＇s phase-shift capability were analyzed and studied carefully from experiments and theory in order to prepare for new optical fibre sensors.
