A polarimeter may include a non-polarizing beamsplitter to split an input beam into a first beam and a second beam, a corner-cube retroreflector to retroreflect the first beam as a polarization-split beam, and a mirror to retroreflect the second beam as a retroreflected second beam. A beam profile of the polarization-split beam includes six regions with different states of polarization associated with a different order of reflections in the corner-cube retroreflector. The non-polarizing beamsplitter may combine the polarization-split beam and the retroreflected second beam as an intensity-split beam having six intensity regions associated with interference of the polarization-split beam with the retroreflected second beam. The polarimeter may further include a detector to measure an intensity of at least some of the six intensity regions and a controller to determine a polarization of the input beam based on the intensities of the at least some of the six intensity regions.
