Abstract
An FBG-based strain sensor equipped with a mechanical te mperature compensation system is proposed. Direct bonding of an FBG element, that is the simplest method to measure strains, may cause broadening of the reflected optical spectrum due to fluctuation of strain distribution of the material under the FBG element. The proposed sensor avoids this difficulty by introducing a mechanism to induce uniform strain distribution to the FBG element. In addition, a simple mechanical system that can cancel the effect of temperature on the strain measurement does eliminate the addition of another FBG sensor for temperature compensation. Extensive tests have been conducted using prototype sensors. The results showed their excellent performance.
