The spectropolarimetry offers, for the remote sensing of the structural features of a plasma entity, a tool which is complementary to all known spectroscopic methods. This technique is based on the fundamental physical concept of the polarization of an ensemble of atomic particles in ionized gases. The general theoretical relations between spectropolarimetric and kinetic parameters describing the particules velocity distribution, that are formulated mathematically making use of the irreducible representations of the three-dimensional rotation symmetry group, allow to derive these kinetic parameters from the measurement of the polarization of light. For this purpose, the principle integral relations connecting the observable polarization of radiation to the anisotropic pressure tensor of the particles responsible for the excitation of the emission spectrum have been derived and analysed in detail (see also /122/). As any spectroscopic technique, the spectropolarimetric diagnostics rely on the inversion of these integral relations.
