The constituent elements of metasurfaces may be designed with explicit polarization dependence, making metasurfaces a fascinating platform for new polarization optics. In this work we show that a metasurface grating can be designed to produce arbitrarily specified polarization states on a set of defined diffraction orders given that the polarization of the incident beam is known. We also demonstrate that, when used in a reverse configuration, the same grating may be used as a parallel snapshot polarimeter, requiring a minimum of bulk polarization optics. We demonstrate its use in measuring partially polarized light, and show that it performs favorably in comparison to a commercial polarimeter. This work is of consequence in any application requiring lightweight, compact, and low-cost polarization optics, polarimetry, or polarization imaging.
超表面的组成元素可以设计成具有明确的偏振依赖性，这使得超表面成为新型偏振光学的一个引人入胜的平台。在这项工作中，我们表明，给定入射光束的偏振，超表面光栅可以设计成在一组定义的衍射级上产生任意指定的偏振态。我们还证明，当以反向配置使用时，同一光栅可以用作并行快照偏振计，只需最少的体偏振光学元件。我们展示了它在测量部分偏振光方面的应用，并表明与商用偏振计相比，它的性能良好。这项工作对于任何需要轻量级、紧凑且低成本的偏振光学、偏振测量或偏振成像的应用都具有重要意义。
