Paper Abstract

Two-dimensional birefringence measurement method using phase shifting technique has been already proposed. However, it has some problem that 16 images data are required for one birefringence distribution analysis and that its accuracy is not highly enough. To overcome this problem, the birefringent distribution measurement method using two special phase shifting techniques to reduce the collected images and to get the high sensitivity relative retardation are established. One is a local-sampling phase shifting technique using the Babinet-Soleil compensator as a phase shifter in order to get high sensitivity. The other is using the one-step phase shifting technique for quick birefringence distribution measurement using a birefringence wedge plate. In this method, only 2 images are enough to analyze the two- dimensional birefringence distribution. These experimental procedures and the results that are compared with the Babinet-Soleil compensator and of the optical components are discussed.
