A channeled spectropolarimetry with increased bandwidth and aliasing reduction that consists of a high order retarder and a Wollaston prism is presented. It has the advantages of compact, low-cost, static and a measurement speed of the complete spectrally resolved Stokes vector [S-0(sigma) S-1(sigma)S-2(sigma)S-3(sigma)](T) around 30 ms. Compared with the conventional channeled spectropolarimetry, it can acquire full resolution S-0(sigma) reconstruction and S-1(sigma), S-2(sigma) and S-3(sigma) reconstruction without errors caused by dominant aliasing between the channels. Besides, the bandwidth of each channel increases by 7/3 times than that of conventional channeled spectropolarimetry. The feasibility of the proposed method is demonstrated by both simulation and laboratory experiments. |
