Spatial coherence of ultrasonic speckle in composites
Pulsed echography in a scattering medium generates speckle noise. Its random nature implies a statistical processing of the backscattered signal. The second-order statistics, such as autocorrelation, can provide information about the structure of the medium and help detect a possible defect. The spa...
