Abstract: (1757 Views)
Raman spectra of TNT and PETN have been recorded on different backgrounds of Aluminum, soil and plastics from a distance of 30 m. Delay and gate time were used in order to eliminate the background fluorescence effect. The effect of applying delay time and gate width was not the same for different backgrounds. The results of this study show the improvement of the signal-to-noise ratio of Raman spectra by applying a gate time for the detector in case of the backgrounds with fluorescence.
