Abstract

The aim of this paper was the verification of our identification model. The main assumption of our model was the possibility of the distinction between indicated compounds based on several narrow band detectors of terahertz radiation. Achieve of this frequency points was done with measurement data from FT-IR obtained in vacuum. The influence of absorption in water vapor was added numerically from Hitran simulation. The verification procedure was carried out with Time Domain Spectroscopy (for distance below 20 cm) and with narrow band sources (for distances above 20 cm). This verification was prepared in laboratory, controlled conditions. Our results confirm the possibility of application of the model in real THz stand-off security system.
