Abstract

This paper describes a modified birefringence measurement using the scattered light method combined with a phase shifting technique. A phase shift between orthogonal linear polarization components is realized by a retardation compensator. The measured distribution has a periodical error, which can be reduced by a band pass filtering of the Fourier spectrum of scattered light distribution. This method enables a birefringence distribution on a light path to be obtained.
