Description

Composite material evaluation still remains a tricky business for various configurations of materials, structures, and of manufacturing and aging processes. The main issue is how to distinguish critical defects in materials which provide naturally a low S/N ratio. Other diagnosis problems such as bounding and water ingress, or corrosion for metallics will benefit from the utilization of signal processing and in particular of the Wavelet Transformation which should offer a more exhaustive and smart approach in signal processing than the standard FFT or Split spectrum procedures.
