Several fiber-optic sensors that are proving very useful for measuring the strain on the surface of structural components are described. The emphasis is on commercially available fiber-optic sensor configurations and instrumentation, as well as on many of the techniques required for successful measurements. Sensor fabrication, optical functionality, multiplexing, demodulation instrumentation, sensor packaging and sensor bonding techniques are all covered.
