Abstract:A set consisting of linear optical retarders, three-dimensional photoelastic models, some crystals, twisted fibres, etc. is optically equivalent to an elliptic retarder, and can be described by its three parameters. New experimental methods for determining the optical parameters of an elliptic retarder are presented with a brief review of the existing methods. The Stokes vector representation of polarized light is used in developing these methods. It is shown that it is possible to find the integral order of t… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
