A Scattered Light Polariscope for Three-Dimensional Birefringent Flow Studies

Abstract
This paper reports in detail the design and construction of a new scattered light polariscope for three‐dimensional birefringent flow research. The unique features of this polariscope, which were employed to overcome the particular problems associated with birefringent flow analysis using scattered light, are pointed out. A photograph of typical birefringence patterns obtainable is shown. A comparison of theoretical and experimental results for a particular flow case is made indicating the accuracy that can be obtained using this polariscope.
