First, a one-dimensional theoretical model is developed. This is based on the cross-correlation function. It is shown that the latter tends to the Green's function. A healthy, then a damaged structure are investigated. Second, an experimental device is set-up to validate the theory. It is based on a pumped water flowing in a tube. The experimental results show a good sensitivity to the damage even if the noise is not perfectly diffused. Furthermore, due to the phase change, the method is robust.Show less >
