Abstract
Characterization of the interaction path of terahertz (THz) waves transmitted through a specifi c material
can be applied to non-destructive imaging and testing. The Advantest TAS7000 3D imaging system
employs non-destructive imaging technology using computed tomography (CT). This system performs
analysis and imaging in both two and three dimensions; enabling identifi cation of specifi c individual
materials in a target sample. One important and unique feature of this technology is the non-destructive
nature of terahertz spectrum analysis, (non-ionic) thus differing from traditional X-ray CT.
