Abstract :
We review recent experiments on the use of terahertz frequency time-domain spectroscopy to sense materials of security relevance. We also explore developments in the use of terahertz quantum cascade lasers to discriminate such materials, and new THz sources that can potentially exploit convenient communication wavelength excitation lasers.
