Abstract

This paper presents an experiment witch use THz radiation for detection and identification of the metallic objects and illegal substances inserted in nonmetallic boxes. Using THz imagistic technique was obtained 2D images of the metallic objects hidden, and with THz spec troscopy was identified the substances from paper box. In this experiment was used the Terahertz Time - Domain Spectroscopy kit from EKSPLA witch have frequency domain 0.1-5THz, and 50GHz precision..

Keywords
