One of these research topics is the study of the measurand optimal transference between the structure and the sensing fiber through the tranducer holder. In the first part of this work, a wide range of fixing techniques and interface materials have been tested. This was achieved by fixing developed FBG based transducers to steel bars. These bars were strained while they were monitorized with conventional strain gauges and professional displacement sensors. Strain transference behaviour was characterized for each transducer type and optimal transducer structures were obtained. After that, steel girder flexural tests were designed and performed. In these tests, both sides of steel girder were monitorized with previously optimal FBG based transducers to characterize their tensional and compression behaviour. Conventional strain gauges where fixed to the steel girder to make comparisons between both technologies.","PeriodicalId":147710,"journal":{"name":"2002 15th Optical Fiber Sensors Conference Technical Digest.

We have recently proposed a novel technique, in which the correlation between two continuous lightwaves is controlled so as to generate the Brillouin scattering position selectively along the fiber. We have demonstrated the spatial resolution of 1 cm in this correlation-based continuous-wave technique. We have also proposed two methods for enlarging the measurement range of this technique. Additionally, we have successfully applied the technique to measure strain distribution on surface of a small ring with only 15 cm diameter. This means the technique is applicable to smart materials.","PeriodicalId":147710,"journal":{"name":"2002 15th Optical Fiber Sensors Conference Technical Digest. OFS 2002(Cat.
