Abstract

Defense and security applications often require definitive and non-destructive testing or identification of samples to enable testers to make effective decisions and preserve potential evidence. Raman spectroscopy has consistently demonstrated its effectiveness as an analytical technique in defense research and applications without interfering with sample integrity. Aiming at the fact that Raman spectroscopy is limited to detect sample composition within the near surface layer or transparent medium, Rutherford Appleton Laboratory proposed the spatial offset Raman spectroscopy. This technique can effectively suppress the powerful Raman and fluorescent signal interference from the surface substance, and realize the composition detection under the opaque diffuse scattering medium material of a few mm or cm. In this paper, we have detected and analyzed the spatially offset Raman spectroscopy of sodium nitrate, sodium sulphate and their mixture powder.
