Abstract
Disclosed embodiments pertain to optical assemblies which impart a spatially dependent rotation to linearly polarized light. A pair of optical assemblies may be used to apply a spatially dependent rotation to linearly polarized light in the region between the optical assemblies, and produce a spatially independent rotation after traversing the second optical assembly. A pair of optical assemblies may be used in combination with a wave plate to allow a determination of the Stokes parameters of an elliptically polarized beam of light.
