Green's function can be retrieved from cross-correlation of a diffuse field generated by noise
sources. Today, this important result is the fundamental of several passive imaging …

Passive listening methodology has been shown to be a practical and effective method for
passive structural health monitoring. In this work, this approach is applied experimentally to …

This article presents an in situ structural health monitoring imaging system for the
localization of impacts on a composite complex structure such as a tail rotor blade. Unlike …

Flow-induced random vibration propagates throughout a plate-like structure and thus
contains information about the structural properties and states. Previous research has …

This paper introduces the concept of secondary noise sources for passive defect detection
and localization in structures. The proposed solution allows for the exploitation of the …

Guided elastic waves emitted by a sensor and propagating to another one are often used as
the physical way of detecting the defect in Structural Health Monitoring (SHM) systems of …

Damage is a prevailing physical phenomenon in in-service structures; accumulation of
damage can cause catastrophic structural failure. For damage identification in plates, the …

The work presented in this paper is concerned with the fundamental study of a damage
detection principle in a reverberant medium, based on ambient acoustic noise correlation …

Recent theoretical and experimental studies have demonstrated that a local Green's function
can be retrieved from the cross-correlation of ambient noise field. This technique can be …

In this paper, phase coherence imaging is proposed to improve spatial resolution and signal-
to-noise ratio (SNR) of near-surface defects in rails using cross-correlation of ultrasonic …
