The non-invasive compositional analysis of diffusely scattering (turbid) samples such as powders, opaque bottles or biological tissues, at depth is a fast evolving area of Raman spectroscopy spurred by the recent advent of Spatially Offset Raman Spectroscopy (SORS). Accessible depths with SORS can be more than an order of magnitude larger than those attainable with conventional Raman spectroscopy enabling, for example, non-invasive interrogation several mm’s, and in some cases several cm’s, deep inside biological tissues. This presentation will focus on the development of SORS , its basic principles and discuss new application areas it is opening, including the detection of explosives in airport security, quality control of pharmaceutical products, subsurface analysis of objects of art and non-invasive cancer and bone disease diagnoses.
