Abstract: Rheo-optical measurements of the flow birefringence, flow dichroism and their respective orientations allow for a detailed direct investigation not only of the configuration of polymers in a flow field but also of the behaviour of associated structures or multiphase systems under flow.
However, the standard setup of an optical train, using phase modulation for the rheo-optical investigation of a chosen flow field, is a rather expensive, complex and delicate structure that needs careful adjustment and calibration. We therefore present a new, simple and robust design of a measurement unit, consisting of several pulsed lasers to determine the desired rheo-optical material functions. Comparison of experimental results to conventional methods will be demonstrated in this paper, as well as the development of a portable stand-alone unit, possibilities of integrating this unit into standard rheometry measurement systems and a tempered high-precision system.
