Disordered metasurface enabled single-shot full-Stokes polarization imaging leveraging weak dichroism [PDF]

Nature Communications, 2023
Polarization, one of the fundamental properties of light, is critical for certain imaging applications because it captures information from the scene that cannot directly be recorded by traditional intensity cameras.
