Abstract

In order to make use of terahertz (THz) spectroscopy technique for homeland security, anti-terrorism, and security inspection, we have examined the applications feasibility of THz spectroscopy to inspect and identify 30 kinds of illicit drugs, 20 kinds of amino acid and 10 kinds of explosives and related compounds (ERCs), respectively. In addition, we also present two reference-free phase feature extraction techniques for identification of ERCs using THz reflection time-domain spectroscopy (RTDS) and transmission TDS, respectively.
