An Algorithm to Identify Material Mixtures from Raman Spectra
Raman spectroscopy is commonly utilized in the field for the identification of bulk powders due to its reliability and high specificity; however, this specificity poses a problem when the unknown bulk powder is a mixture. Each mixture produces unique spectra at different concentrations (non-linear) and current algorithms or systems are not proficient at identifying mixtures based on the pure components recorded in its library. In the field of explosive detection, this poses a problem when dealing with homemade explosives (HMEs) especially oxidizer/fuel mixtures. Vendors have attempted to address this issue with their Raman systems; however, they have not yet found a robust solution.
