Abstract
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 [S0(σ) S1(σ) S2(σ) S3(σ)]T around 30 ms. Compared with the conventional channeled spectropolarimetry, it can acquire full resolution S0(σ) reconstruction and S1(σ), S2(σ) and S3(σ) 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.
