Paper Abstract
A new fiber-optic acoustic/vibration sensor has been developed. The sensor is based on Doppler effect in flexible and expandable light-waveguide (DEFEW). The DEFEW sensor has extremely high sensitivity in wide band of frequency range. The sensing technology is applied to high speed phenomena, for examples, breakage of carbon fiber in matrix resin and elastic wave propagation impacted by electrical discharge. The demonstrated results show that the DEFEW sensor is applicable to nondestructive damage detection for structural health monitoring.
