HMI Image Map.
HMI consists of a refracting telescope, a polarization selector, an image stabilization system, a narrow band tunable filter and two 4096 pixel CCD cameras. It observes the full solar disk in the Fe I absorption line at 6173 Angstrom with a resolution of 1 arc-second. HMI takes images in a sequence of tuning and polarizations at a 4-second cadence for each camera. One camera is dedicated to a 45 s Doppler and line-of-sight field sequence while the other to a 90 s vector field sequence.
