| Abstract | A sensitive, non-destructive and highly selective method of standoff detection using coherent anti-Stokes Raman spectroscopy (CARS) is presented. The approach uses a single amplified femtosecond laser to generate high resolution (<10cm) multiplex CARS spectra encompassing the fingerprint region (400cm – 2500cm) at standoff distance. Quantitative studies of this method result in detection of 2μg/cm of an explosive simulant in a complex background and retro-reflecting conditions. Additionally, a standoff imaging modality is introduced, visually demonstrating similar sensitivity and high selectivity including isomer discrimination. |
