Abstract
A novel inversion algorithm has been developed which combines a “macro” layer-stripping approach with high resolution, L2-norm deconvolution. This algorithm has been implemented for real time data acquisition using a TMS 320C30 digital signal processor as well as for post-processing of the ultrasonic data. A further optimization-based procedure may also be applied, provided there exists adequate prior knowledge concerning the structure. Applications for these algorithms will be demonstrated for the detection of disbonds and delaminations in aircraft composite structures.
