| dc.description | The photoelectric polarimeter which is described associates the three major discoveries of B. Lyot: the coronagraph, the birefringent filter and the polarimeter. However it differs completely from the coronameter. It is possible to study many emission lines by tuning the birefringent filter. But the D<sub>3</sub> helium line is mainly used.In 10 s of time, the polarimeter measures in a 5" diameter spot three quantities: monochromatic intensity, polarization ratio p, angular deviation from the limb: e. The instrument gives a polarimetric map of the prominence. Owing to its performances, it is possible to study fast moving objects such as active prominences. |
