Abstract :
We present a novel THz-TDS system used for the identification of defects in joint plastic. The system utilizes two delay lines, one long, for defect location and the other short, for imaging of the defect. Cross-sectional THz images that reveal defects (air gaps) are been confirmed using CT measurements.
