This study demonstrates the separation of the finite electron temperature on the plasma polarimetry in the magnetic confined fusion plasma for the first time. Approximate solutions of the transformed Stokes equation, including the relativistic effect, suggest that the orientation angle, θ, and ellipticity angle, ε, of polarization state have different dependency on the electron density, ne, and the electron temperature, Te, and that the separation of ne and Te from θ and ε is possible in principle. We carry out the equilibrium and kinetic reconstruction of tokamak plasma when the central electron density was 1020 m-3, and the central electron temperatures were 5, 10, 20, and 30 keV. For both cases when a total plasma current, Ip, is known and when Ip is unknown, the profiles of plasma current density, jϕ, ne, and Te are successfully reconstructed. The reconstruction of jϕ without the information of Ip indicates the new method of Ip measurement applicable to steady state operation of tokamak.
