基于磁致伸缩的光纤传感器技术
|
摘要
主要利用磁致伸缩原理构建出光纤传感器,并在理论上讨论了影响灵敏度的两个因素.为下一步利用该传感器对地球磁场进行测量,对地震的发生地点和强度进行预测,减少或避免地质灾害对人民生命财产造成的损失做准备.
The optical fiber sensor based on magnetostriction has high magnetostriction sensitivity and anti-jamming.The sensor can be used to measure earth-magnetic so that earthquake would be forecasted the site and intensity.The text mostly introduces structure,sensitive and theory of magnetism optical-fiber sensor with discussing the influencing factor of sensitive
