Abstract

This article provides information about using terahertz radiation based methods such as time-domain spectroscopy, ATR spectroscopy and terahertz reflection imaging for distinguishing of different kinds of gunpowder. The findings in this article prove that gunpowder does not have any sharp peaks in terahertz region of electromagnetic spectrum up to 2.5 THz, but also prove that distinguishing of different kinds of gunpowder is possible using different methods based on terahertz radiation. All presented results are connected to absorbance of gunpowder and other measured materials, because comparison of absorbance analysis is essential for distinguishing of gunpowder samples.
