Abstract

Redondo Optics Inc. in collaboration with the Cortland Cable Company and the US. Navy under a Navy sponsored SBIR program is in the process of developing an embedded distributed fiber optic sensor (EDIFOS^TM) system for the real-time, structural health monitoring, damage assessment, and lifetime prediction of full scale synthetic material arresting gear cables. The EDIFOS^TM system uses a distributed array of fiber Bragg grating sensors, sensitive to stress/strain, impact damage, kinking and bending, and temperature, embedded within the strands of a synthetic material arresting cable structure. Fiber Bragg grating sensors are a mature technology typically used for the in-situ structural health monitoring of advanced structures. The periodic grating produces an optical, wavelength-encoded signal whose properties are dependent on the structural, and mechanical environment of the sensor fiber. The FBG sensor interrogation system monitors the status of each of the individual FBG sensors distributed along the embedded sensor fibers and transforms this information in real-time in to a graphical display of the stress/strain and temperature state of the entire arresting gear cable. An alarm system triggers to pinpoint those locations of potential damage.
