Abstract:
Active InfraRed Thermography (IRT) is an emerging te
chnique in the field of Non-Destructive Testing and
Evaluation (NDT&E). In recent years, pulse compressi
on supportive techniques and associated data proces
sing
schemes have been proposed by various research grou
ps to enhance the inspection capabilities of these
techniques as
well as to make the experimentation simple and more
reliable. This paper exploits a suitable complemen
tary coded
excitation for thermal NDT&E along with the associat
ed pulse compression favorable data processing sche
me. The
proposed scheme has been implemented on a metallic
sample in order to test its capabilities for subsur
face defect
detection and characterization.
