Keywords:metasurface, polarimeter, polarimetric imaging

Polarimetric imaging is expected to be applied in various fields. By using metasurfaces, the complete detection of polarization states, including circular polarization, can be achieved compactly. However, the demonstration has had problems in terms of efficiency and resolution. In this paper, we propose and demonstrate a polarimeter using a metasurface that can detect full Stokes vectors in a lossless and sensitive configuration. Furthermore, our polarimeter can be compactly realized with only four pixels, which is the smallest in principle.
