Abstract

This study examines using simulated spectra for analysis of diffuse IR reflectance from explosive materials that are sparsely distributed upon a surface. The simulated spectra are calculated using ensembles of reflectance spectra for non-interacting explosive particles on surfaces, which have specified dielectric response properties and particle-size distributions. Reflectance spectra for individual particles upon a surface are calculated numerically using a model based on Mie scattering theory, which assumes a spherical particle on a surface. This validation study considers a prototype system comprising a sparse distribution of RDX particles upon a soda-lime glass surface compared with experimental results.
