The received signal amplitude as a function of the incidence angle depends highly on the elastic parameters and thickness of the layers. The same problem is treated also theoretically. The experimental results are compared with theoretical predictions and they are found to be in good agreement.

Fr. Schultz,A. Götte,W. Petersenrface areas which are devoid of adhesive, have trapped gas, are not chemically bonded by the adhesive or are simply in mechanical contact, form areas of delaminations detrimental to the performance of these components.

The performances and computational complexities of these algorithms are analyzed and compared. In addition, application of these deconvolution techniques to B-scan enhancement is also discussed.
