This paper presents the results of an optical anisotropy study of a polymer film and the effect of
temperature on birefringence. A method using a polariscope for the quantitative determination of the
optical path difference is offered. The research findings are useful to students of physical and
engineering specialities studying electromagnetic theory and optics. The described experiments and
theoretical approaches are based on prominent aspects of modern optics. This work can be used to
teach students the methods of polarimetry, the method of measuring optical anisotropy, and the
basics of colorimetry. Students will learn a color description system to demonstrate the
interference of polarized light, as well as being able to make a comparison between the numerical
simulation and experiment of the interference pattern.
