Calculation of the Mean Strain of Smooth Non-Uniform Strain Fields Using Conventional FBG Sensors
Journal of Lightwave Technology(2018)
摘要
In the past few decades, fiber Bragg grating (FBG) sensors have gained a lot of attention in the field of distributed point strain measurement. One of the most interesting properties of these sensors is the presumed linear relationship between the strain and the peak wavelength shift of the FBG reflected spectra. However, subjecting sensors to a non-uniform stress field will in general result in a...
