SO-PHI, Polarimetric and Helioseismic Imager on Solar Orbiter

The Polarimetric and Helioseismic Imager is a magnetograph based on two telescopes, the Full Disc Telescope (FDT) and the High Resolution Telescope (HRT). The instrument carries out narrow-band imaging spectro-polarimetry of the Fe I 617.3nm absorption line, obtaining four polarization states at each of the six spectral scanning position. In their more extended version, the scientific data provided by SO/PHI consist of the Stokes vector, the full magnetic field vector, the Doppler velocity as well as the continuum intensity at each pixel in the field of view.
