SO Colloquium – Metasurface enabled astronomical polarimetry

The nanotechnology of metasurfaces is rapidly changing the landscape of applied optics. While traditional lensing systems may not benefit significantly from the new technology, the ability of metasurfaces to manipulate light and its polarization state offers great advantages in applied polarimetry, as in the case of the magnetic diagnostics of astrophysical plasmas. The Solar Imaging Metasurface Polarimeter (SIMPol) was a NASA funded project to demonstrate such a capability and advance the TRL of metasurfaces for application to polarimetrice observations from space.

We present the general concept of metasurface-enabled spectro-polarimetry, as well as preliminary results from the test campaign of SIMPol at a major solar research facility.
