We use OCT-based technology for quantitative optical sensing of solids and fluids. Here you find an overview of the research activities in this area.
Optical coherence tomography can be used for path-length resolved detection of ligh transmitted through a turbid medium. From the phase and amplitude of the transmitted ballistic light both group refractive index and optical attenuation coefficient can be quantified. For a binary compound fluid we used this for glucose sensing. We are working on extending this principle to multi-component systems and combining this sensing principle with other fluid parameters.
