WebbRaman spectra were recorded at a spatial offset of 15 mm with 200 mW laser power at the sample for the synthetic phantom and 300 mW for the ex vivo porcine tissue, with 30 s × 10 accumulations in the spectral range ∼100 to 1900 cm −1 at a spectral resolution of ∼8 cm −1 . Results and discussion Spatially offset Raman spectroscopy (SORS) is a variant of Raman spectroscopy that allows highly accurate chemical analysis of objects beneath obscuring surfaces, such as tissue, coatings and bottles. Examples of uses include analysis of: bone beneath skin, tablets inside plastic bottles, explosives inside containers and counterfeit tablets inside blister packs. There have also been advancements in the development of deep non-invasive medical diagnosis using SORS with th…
