Abstract :
This paper describes an example of using a compact Terahertz (THz) system to analyze the layered structure of a composite plastic samples in a non-destructive manner. Time-domain data is analyzed to measure the thickness of each layer of the sample and determine the presence or absence of adhesive bonding the plastic parts. The presence and position of the adhesive is clearly visible in the THz images and the measured thickness shows an excellent agreement with nominal thickness.
