Abstract

High-density optical arrays of fluorescent micrometer sized sensors show promise for detecting low level vapor phase explosives and explosives-like compounds. Imaging software and a high-speed CCD detection system are used to capture changes in a temporal response pattern upon pulsatile vapor delivery to the sensors. Nitroaromatic compounds, such as 2,4-dinitrotoluene (DNT) and 1,3-dinitrobenzene, which are often present on the solid surface above buried landmines, are used to train pattern recognition networks for vapor phase detection. We have demonstrated previously that approximately 9 ppb 2,4-DNT can be detected when signal processing schemes are employed.
