Innovative Detection Technologies

LDS’s detection systems rely on Ion Mobility Spectroscopy (IMS) to detect trace quantities of low-volatile organic substances in extremely low concentrations, thus providing best-in-class sensitivity and probability of detection. 

Other chemical sensing and detection technologies used by LDS utilize Laser Spectrometry and Wet-Chemistry techniques, all providing the most comprehensive and accurate detection and identification of explosives, narcotics, and hazardous chemicals substances.

Detection methods relying on Wet-Chemistry provide a highly reliable, and cost-effective technology based on chemical reagents that change color upon contact with a suspicious substance. LDS explosive detection testers based on wet-chemistry detect 99% of explosives on the FBI Threat List.

LDS implements spectrum processing algorithms and various processing, data fusion and filtering methods including RAMAN, UV-RAMAN, luminescence and Laser-Induced Breakdown Spectroscopy (LIBS).

In Raman Spectroscopy, a laser source illuminates a spot on the surface being scanned, whether vehicle, drum, left-behind luggage, etc. Any explosive residue present on the object produces Raman scattering. Then, the scattered light is collected by a telescope and analyzed by a spectrometer and detector. A spectral fingerprint (i.e., the Raman spectrum) is generated in as little as 5-20 seconds. Finally, the spectrum is compared with previously recorded Raman spectral analysis to identify suspicious substances.
