Detection of heterogeneities within a scattering medium using Raman spectroscopy

A micro-Raman apparatus was used to detect an object embedded within a scattering medium. The Raman vibrational frequency of diamond in an intralipid scattering medium was detected at different radial distances from the diamond. Scanned images of a single diamond, two diamonds, and a diamond through an aperture are presented. This experiment shows that Raman spectroscopy can be a useful tool in locating and characterizing heterogeneities contained within a scattering medium.
