Wide field snapshot imaging polarimeter using modified Savart plates

Abstract

Without moving parts, the snapshot imaging polarimeter utilizing Savart plates is capable of stable and fast measurements of spatiallly distributed Stokes parameters. To increase feasibility of the optical design, we propose modifications that enable a wider field-of view. By changing the Savar plates' configuration and improving the calibration procedure, the unwanted effects associated with the increase in the field of view can be reduced. We carried out the verification experiments of the wide field of view snapshot imaging polarimeter. © 2013 SPIE.
