Potential Low-Cost Optical Fiber Bragg-Grating Sensor Systems for Structural Health Monitoring and Examples of their Application

摘要

Potential low-cost strain, vibration and temperature sensor systems based on draw-tower fabricated fiber Bragg grating arrays and spectral high-resolution polychromator interrogation have been developed. Performance has been demonstrated in field tests of electric power generators, aircrafts and spacecraft structures, railway tracks, and in rock-bolts for mining and geotechnical engineering.
