Abstract

We have designed an optical apparatus which probes the full stress tensor using a single flow cell. The innovation of this work is to send light at multiple angles with respect to the flow. At an arbitrary angel, the birefringence depends on all three material functions. Different angles can be sampled at the same strain to calculate the three independent stress components. The data collected to date illustrate the soundness of the technique, while improvements to the apparatus should allow quantitative measurements of the full stress tensor.
