Paper Abstract

In this paper we describe and compare two methods for detecting Lamb waves used for damage detection. One is a polarimetric sensor that integrates the pressure effects of the acoustic wave along its length, whilst the other is the Bragg grating that measures linear strain and is in effect a point sensor. Both sensors are highly directional, which gives benefits in damage signal detection and source location. We demonstrate both the detection and location of damage and discuss the advantages and disadvantages of the two sensors.
