20 Defence R&D Canada – Valcartier R & D pour la défense Canada – Valcartier Questions ?

21 Defence R&D Canada – Valcartier R & D pour la défense Canada – Valcartier Differential Spectroscopic Techniques Existing and Potential Standoff Explosives Detection Techniques Committee on the Review of Existing and Potential Standoff Explosives Detection Techniques, National Research Council, The National Academies Press, 148 pp., Washington, D.C., 2004 Download free sample PDF : Important recommendation stated: Research in the IR spectral range is needed to study the spectroscopic properties (e.g., thermal emissivity versus wavelength) of human skin, clothing, and other relevant materials. This information might lead to differential spectroscopic techniques that could improve IR imaging for explosive detection.
