Description

Fiber optic sensors have emerged as important sensing devices for the detection of a broad range of physical parameters. In many applications they offer a number of advantages over traditional sensing elements, including small size, light weight, immunity to electromagnetic interference, and the ability to operate at elevated temperatures [1]. Fiber optic sensors when configured for the detection of ultrasound have potential for use in nondestructive evaluation applications. However, a drawback associated with fiber optic ultrasound sensors is their lower sensitivity when compared to traditional piezoelectric transducers. In this work, the sensitivity of an embedded fiber optic Fabry-Perot ultrasound sensor has been investigated.
