Abstract
New method in plasma polarimetry is considered, which is based on the phenomenon of normal wave transformation in the vicinity of orthogonality point, where the probing beam is perpendicular to the static magnetic. Phenomenon of normal wave transformation near orthogonality point is analyzed in the frame of quasi-isotropic approximation of geometrical optics, both theoretically and numerically. It is shown that measuring polarization state of the beam, passing through the orthogonality point allows estimating local electron density in the vicinity of that point. This property seems to be great advantage of the method under consideration as compared with traditional plasma polarimetry, which deals with line averaged measurements.
