Abstract: | Spectroscopy in the terahertz frequency range has demonstrated unique identification of both pure and military-grade explosives.
There is significant potential for wide applications of the technology for nondestructive and nonintrusive detection of explosives
and related devices. Terahertz radiation can penetrate most dielectrics, such as clothing materials, plastics, and cardboard.
This allows both screening of personnel and through-container screening. We review the capabilities of the technology to detect
and identify explosives and highlight some of the critical works in this area. |
