Short-wave infrared excited spatially offset Raman spectroscopy (SORS) for through-barrier detection

Author affiliations

Abstract

Spatially offset Raman spectroscopy (SORS) using 1064 nm excitation is demonstrated here to detect chemicals through a physical barrier such as a container. This excitation wavelength overcomes the issue of fluorescence from the target chemical, whilst retaining the benefits of the SORS technique for through-barrier detection. These advantages have a wide range of applications in both civilian and military environments.
