SFSI Instrument

Measurements and Applications

SFSI uses the Fe and Hα spectral lines to scan the solar photosphere and chromosphere, respectively. It can obtain the spectral information at any position on the solar surface, thereby accurately calculating the velocity field of photosphere and chromosphere.
