【Abstract】 WT5”BZ]:This paper brings out an optic fiber strain sensor based on an optic fiber strain gauge.Monitoring the bending loss of optic fiber bonded on the optic fiber strain gauge,the strain and the deformation can be obtained.The measuring results for the micro displacement and the strain indicate that the optic fiber strain gauge offers a monitoring method both strain and distortion.And the strain response of the optic fiber strain gauge is more sensitive than the one of resistance strain gauge.更多还原
