Optical Coherence Tomography (OCT) has opened whole new possibilities for measuring boundary layer properties for opaque fluids. Our results clearly demonstrate the benefits of having direct measurement of the velocity field inside the rheometer instead of using assumed velocity profile as the basis of interpreting the measured rheometric data. OCT has the potential of significant breakthrough in understanding the rheological properties of complex opaque fluids such as MFC. By utilizing this method we have obtained new information about flow instabilities inside a rheometer gap and used this data to interpret rheometer flow curve.
