Line-scan Raman spectroscopy for detection and imaging of explosives traces by a compact Raman spectrometer Academic Article uri icon

abstract

  • Abstract Measurements of Raman scattering spectra and of Raman maps of particles of explosives and related compounds [potassium nitrate, 2, 4-dinitrotoluene (DNT), 2, 4, 6- trinitrotoluene (TNT) and 1, 3, 5-trinitro-1, 3, 5-triazacyclohexane (RDX)] were performed by a homebuilt compact Raman system, functioning with a 532-nm laser beam, focused as a point or line, along with full vertical binning or image readout of an intensified charge- coupled device camera. High specificity and sensitivity were obtained by line-excitation, which allowed fast detection and mapping of explosive particles with a relatively simple system.
