Abstract
Strain, deformation and temperature measurements constitute the most interesting parameters to be monitored in smart structures. White-light interferometry offers these performances even for long-term measurements. Based on the Michelson interferometer, a fiber optic localized strain sensor and multiplexing strain-sensing techniques are demonstrated in this paper. Related problem about the spatial division limitation of fiber optic sensors is discussed. Finally, application examples such as cable strain measuring of cable-stayed bridge model, inside strain measurements for concrete specimens and temperature monitoring are also given.
