Abstract

We propose a two-dimensional birefringence measurement method. A linearly polarized light goes through a Babinet-Soleil compensator whose principle axis direction is set 45 degree to the incident light. The light is affected by the birefringence when it passes through an optical sample. The interference fringe behind a linear polarizer is captured wholly as a two- dimensional image by a CCD camera. The data is analyzed into the phase information by the phase shifting technique using a Babinet-Soleil compensator. Here the obtained phase changes sinusoidally. Its amplitude and phase mean the relative retardation and azimuth angle respectively when a polarization azimuth of the incident light is rotated. A half-wave plate as a phase shifter is used again to obtain this amplitude and phase using the phase shifting technique again. We discuss these experimental procedures and results applied to such optical components as a lens and a roof prism.
