Abstract

Fiber optic grating sensors can be used to measure multi-dimensional strain, pressure, temperature, corrosion and moisture. The application of this technology to structural health monitoring of aerospace platforms includes adhesive bond line measurements, crack detection, damage assessment of composite and moisture/corrosion sensing. One very important application is the emerging field of "strain imaging" that can be used in certain situations to detect, localize and characterize damage in composites. This paper will provide an overview of some of the techniques that have been applied using fiber grating sensors to monitor structural health and comparisons will be made to more traditional methods such as ultrasonic and eddy current scans.
