Lamb Wave Detection for Structural Health Monitoring Using a ϕ-OTDR System

Lamb Wave Detection for Structural Health Monitoring Using a ϕ-OTDR System

In this paper, the use of a phase-sensitive optical time-domain reflectometry (ϕ-OTDR) sensor for the detection of the Lamb waves excited by a piezoelectric transducer in an aluminum plate, is investigated. The system is shown to detect and resolve the Lamb wave in distinct regions of the plate, ope...
