Method of obtaining concurrent measurements of circular and linear birefringence

In a system which exhibits both circular and linear birefringence one can obtain the magnitude of each component. The measuring system consists of a quarter wave plate, a polarizing and an analysing prism. By rotating the quarter wave plate and the analysing prism independently a complete extinction can be obtained. A demonstration is given of a method which uses the Jones calculus to calculate the magnitude of both the circular and linear birefringence from the quarter wave plate and the analyser azimuths.
