Navy Pairs Thermal Imaging with Spectroscopy for Standoff Chemical Detection

Detecting trace quantities of explosives, chemical or biological agents on a variety of surfaces is challenging—especially from a distance without physically collecting a sample. Spectroscopic techniques have been used, but even though they can be highly selective, they have poor sensitivity. Researchers are increasingly using thermal infrared imaging techniques because they can be safely used
