Defect Detection via THz Imaging: Potentials and Limitations

Until recent years, terahertz waves were an
undiscovered, or most importantly, an unexploited
area of electromagnetic spectrum. Recent advances in
hardware have started to open up the eld to new
applications such as THz imaging. This non
destructive technology can penetrate through diverse
material such that the internal structure which is
invisible to other imaging modalities, can be
visualized. However, automated processing of THz
images can be quite challenging. Low contrast and the
presence of a widely unknown type of noise make the
analysis of these images difficult. Therefore,
pre-processing techniques are required for further
investigations.
