摘要:
研究了全光纤Mach-Zehnder干涉实验系统,并将其用于微应变的测量.介绍了全光纤M-Z干涉仪测应变系统的基本结构和原理,讨论了应变量的计算方法.通过实验,测量了不同应变情况下的几组信号,并对数据分析处理,解调出包含在干涉信号中的应变信息.实验装置简单,易操作.实验结果表明,全光纤Mach-Zehnder干涉仪与电传感器实验仪相比较,具有更高的频率响应和测量灵敏度.
Abstract:
An a ll??fibe rM ach Zehnder interfe rence sy stem w as resea rched and used to m easure the m icro strain. The basic structure and theo ry o fM ach Zehnder in terferencem easurem ent sy stem w ere introduced, and the signa l processing techniquew as d iscussed. Severa l g roups of the inte rference signa ls unde r d iffe rent stra in cond itions w ere m easured through the exper iment, and the data w ere ana lyzed and processed, and the stra in inform ation w as dem odu la ted out o f the in terference s igna ls. The expe rim en t dev ice is uncomp licated and easy to operate. The result of the experim ent prov ed that com pared w ith the sensor exper im ent dev ice, a ll fibe rM ach Zehnder interfe rome ter has higher frequency re  sponse and sens itiv ity.
