Structural Health Monitoring using time reversal techniques in acoustic domains
Abstract
An increasing interest for Structure Health Monitoring (SHM) has been observed during the last decades.
Monitoring solutions have then been developed to detect flaws in structure at an early stage in order to anticipate
on maintenance. In this paper, focus have been made on time reversal techniques in acoustic domain (up to
10kHz). Devices suitable for in field instrumentation have been developed and have shown good results for
sub-wavelength sized flaw detection.
