摘要：
We describe a fiber optic Bragg grating distributed strain sensor system for large scale structural monitoring applications, such as bridge monitoring. The system is capable of assessing both long term static structural loading changes and dynamic/modal behavior of the structure using two different optical interrogation schemes to address the same sensor array. The system has been used to monitor over 45 sensors attached to or embedded in a single-lane bridge span, for damage assessment.
