Paper Abstract

The phase shifting technique for the measurement of a twodimensional birefringence distribution is described and discussed. The birefringent phase difference and azimuthal angle of a transparent material can be determined in the dependence of both measurements on the amplitude and phase of the polarization interferometry. A half-wave plate and a Babinet-Soleil compensator are used as phase shifters for the phase shifting technique. It can measure 256 x 256 values of the birefringent phase difference and azimuthal angle in a short time with sufficient accuracy. This method does not require moving the sample mechanically. The results and procedures for measuring such a birefringence distribution of optical components such as a calibrated Babinet-Soleil compensator, a lens, and a roof prism are discussed.
