Paper Abstract

In this paper, we have developed a spectroscopic topological Stokes polarimeter using an axisymmetrical quarter wave plate (AQWP). The AQWP is fabricated by the alignment of segments of quarter wave films. The azimuthal angles of the polarization element are changed in according with its own segment. This element works as same the technique as the rotating quarter wave plate. In the experiment, we evaluated birefringence distribution of the AQWP. By changing a position of polarized singularity point in the beam spot, we can measure states of polarization. We demonstrate that the change of polarization states is corresponded with the change of the polarized singularity points.
