| Abstract: | A method for surface strain measurement based on the multi-mode optical fiber speckle was presented.The paper analyzed the basic theory of this method and designed the testing device.The paper also showed how to sample the data,fit the polynomial curve and compute the strain value by using the LabVIEW software.The measuring result has been obtained by experiment and its corresponding analysis were shown.The result shows that this method is suitable for surface strain measurement.The system is simple and has high work reliability and good application prospects. |
