Imaging Fabry-Perot Interferometer (FPI)

The UCL Imaging Fabry-Perot Interferometer (FPI).

 Scientific objectives
Observations of the polar thermosphere and ion-neutral coupling studies, particularly meso-scale structures. The FPI provides line-of-sight thermospheric winds and temperatures in several cardinal directions.
