摘　　要：We report a new method to deeply analyze the scrambling characteristic of polarization scramblers based on density of polarization states(DPS)statistics that makes it possible to describe the DPS distribution in detail on the whole Poincarésphere,thus easy to locate accurately the nonuniform areas of defective polarization scramblers,which cannot be realized by existing methods.We have built a polarization scrambling system to demonstrate the advantages of our method compared with others by experiments and suggested effective evaluation indexes whose validity is well confirmed by applying to a commercial scrambler.Our conclusions are valuable for accurately analyzing and diagnosing the performance of any polarization scrambler,and quality evaluation of polarization controllers or other polarization devices.
