Terahertz spectroscopic identification of explosive and drug simulants concealed by various hiding techniques

Appl Opt. 2015 May 10;54(14):4495-502. doi: 10.1364/AO.54.004495.

Abstract

Terahertz time-domain spectroscopy and imaging is used to study the effects of various hiding techniques of spectral features of drug and explosive simulants in combination with different paper and textile barriers. Results show that rapid detection and identification of concealed simulants is possible in the frequency range from 1.5 to 4.0 THz by using an organic-crystal-based terahertz time-domain system and the spectral peak analysis method.
