Abstract :
Summary form only given. T-ray computed tomography imaging has significant potential in a number of applications. It is capable of reconstructing the 3D structure and frequency dependent far-infrared optical properties of an object. Using the reconstructed material properties different substances may be uniquely identified despite being hidden within other opaque structures. Applications of this technology are foreseen in non-destructive mail/packaging inspection, semiconductor testing, quality control of plastics and certain biomedical applications where the absorption of THz is not prohibitive.
