Paper Abstract

This paper describes two designs for beam combiners which measures all of the Stokes parameters. The first is the combination of a optical polarimeter for a single telescope with a simple beam combiner. The second approach forms 2N beams by splitting the light from each of the N telescopes into orthogonal, linear polarizations. Then, those 2N beams are fed into a single, multi-beam combiner. We present optical designs for both systems. We claim the second design is simpler and has the advantage of being easier to calibrate.
