Abstract : This work deals with the development of fiber-optic ultrasound sensors. A frequency-stabilized fiber-optic fabry-perot (FST-FOFP) sensor has been devised. The sensor has been used to detect pzt and laser-generated ultrasound. Applications to flaw detection have been demonstrated. Theoretical calculations have been performed to obtain the frequency response of the FSI-FOFP embedded in epoxy, and the calculations have been verified experimentally.
