摘要
介绍了如何利用美国ＮＩ公司的ＬａｂＶＩＥＷ软件开发实时处理应变光纤传感器测量的数据。这种方法可以通过内插和ＦＦＴ（快速傅立叶变换）基本上实现对应变的实时测量，文章最后给出了一个利用ＩｎｂＶＩＥＷ进行处理的程序。
This paper introduces how to use LabVIEW(A workbench produced by National Instruments Company) to process nearly real-time the data acquired by OPDs (Optical path length difference) optical fibre sensor using a white light source and a CCD (charge-coupled device) based monochromator for strain gauged.This method can in substance realize real-time measurement the strain of a structure in spectral analysis by using Spline Interpolant and Fry, Finally we should give a program writed by LabVIEW to show the result.
