ABSTRACT:
A polarimeter simultaneously measures the Stokes vectors of a light beam using an optics unit with a slit with a slit axis, a foreoptics that focuses the light beam from the point location through the slit, a collimator that receives the light beam from the slit and collimates the light beam, a cylinder lens that receives the light beam from the collimator, wherein the cylinder lens has a cylindrical axis parallel to the slit axis, a re-imaging lens that images the light beam from the cylinder lens onto a focal plane, and a set of polarizing filters including three polarization filters having three different polarizations. The polarization filters are adjacent to each other in a direction perpendicular to the slit axis and lie between the cylinder lens and the focal plane so that the light beam is directed onto the set of polarizing filters.
