Depolyment of a fiber Bragg grating-based measurement system in a structural health monitoring application

The development and maturation of fiber optic sensor technology has been an increasingly important component of the structural health monitoring field. A strain sensor system has been developed to provide high-resolution, low-noise sets of useful data which can be analyzed and processed with a number of existing damage detection techniques. Recent research at the Naval Research Laboratory has also begun in combining vibration-based damage detection with statistical methods, and some preliminary results are included.
