Abstract
The article presents tests of samples containing defects that may occur in composite and hybrid structures used in aviation. The studies were carried out using a time domain spectroscopy (TDS) scanner. Moreover, an attempt was made to automate the analysis of the obtained results, thanks to the application of the method of dynamic time wrapping (DTW). The paper uses the DTW method to automatically compare time signals without defects (reference) and signals potentially having defects, which then made it possible to locate defects in the tested composite plate and determine the depth of their occurrence.
