Algorithms for Structural Dynamics Based Fiber Optic Strain Gage Health Monitoring

San Diego Composites Inc. (SDC) will develop techniques for the reduction and analysis of fiber optic data with a focus on developing associations between frequency domain behavior and structure aging and damage. The algorithms would relate changes in frequency domain behavior to changes in material energy interaction due to quantified material property change. The algorithms will also be coupled with visualization techniques which can help show changes in structural behavior compared to the baseline. In addition, the proposed algorithms would couple with fiber optic strain gage research that SDC is performing on other SBIR programs with a focus on the development of an integrated fiber optic SHM system. SDC believes that maintaining a focus on the full-scale system helps to better shape and direct the work on each component part of the system.
