LabVIEW在光纤Bragg光栅解调系统中的应用

目前多数光纤Bragg光栅解调设备只是测出绝对波长，解调设备附带的解调软件也只是实时显示波长，这大大限制了解调设备的应用。sm125是美国MOI公司生产的光栅传感解调模块，现对基于模块sm125和TCP／IP协议的数据采集处理系统使用LabVIEW语言进行二次开发，形成了界面友好的光栅传感解调软件系统，可实现被测物理量的实时显示、监控和数据库存储等功能，从而使模块sm125的解调系统更加实用化。不但使用户使用起来更直观，而且存储的数据有利于以后的数据分析和诊断。

Application of LabVIEW on Fibre Bragg Grating demodulation system

At present most demodulation devices for Fibre Bragg Grating just detect the absolute wavelengths,and the accessory demodulation software just displays measured wavelengths and stores them,Which greatly limits the application of demodulation devices.The module sm125 is produced by Micro Optics Inc of United States.A secondary development of the data retrieval and processing software based on the sm125 module and TCP/IP had been done in this article,a friendly user interface was formed at last,and the software could monitor and store the interrelated data.So the demodulation module sm125 becomes more practical.For the user,it's more intuitionistic and the stored data can be used for after analysis and diagnosis.
