Abstract: Many well-known explosive detection techniques such as mass spectrometry and chromatography rely on close-contact sampling of surface residues or explosive vapors. Effective detection of explosive materials using laser-based methods has been demonstrated in close-contact and standoff (tens of meters) configurations. This work reviews the current technical progress in laser-based explosive detection methods such as infrared spectroscopy, Raman spectroscopy, terahertz spectroscopy, laser-induced breakdown spectroscopy, and photofragmentation. The potential for standoff detection using these techniques is also discussed.
