Abstract
A polarimeter for receiving input electromagnetic radiation characterized by a polarization state and for determining the polarization state. The polarimeter includes a refractive arrangement for refracting the input electromagnetic radiation so as to provide a spatial pattern corresponding to the polarization state, and an image analysis arrangement for receiving the spatial pattern, producing an electronic image of the spatial pattern, and for determining the polarization state of the input electromagnetic radiation according to the electronic image of the spatial pattern.
