Paper Abstract

Reliable active and passive hyperspectral imaging and detection of explosives and solid-phase chemical residue on surfaces remains a challenge and an active area of research. Both methods rely on reference libraries for material identification, but in many cases the reference spectra are either not available or do not sufficiently resemble the instrumental signals of light reflected, scattered, or emitted from real-world objects. We describe a physics-based model using the complex dielectric constant to explain what is often thought of as anomalous behavior of scattered or nonspecular signatures encountered in active and passive sensing of explosives or chemicals on surfaces and show modeling and experimental results for RDX.
