Optical Sensing


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 Sensing

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.
