The method of localized polarimetric measurements based on the phenomenon of modes conversion near the orthogonality point between the electromagnetic beam and one of the helical magnetic lines in a tokamak plasma is discussed. A simple model of toroidal magnetized plasma is suggested, which allows one to analyze the applicability of localized polarimetry for the ITER project. It is shown that an acceptable localization of polarimetric measurements of about 0.3 m can be achieved for very high densities of order Ne = 1017 cm−3, which are significantly higher than the plasma densities, Ne = 1014–1015 cm−3, envisaged for the ITER project.
トカマクプラズマにおける電磁ビームと螺旋磁力線の間の直交点付近でのモード変換現象に基づく局所偏光測定法について論じる。トロイダル磁化プラズマの簡単なモデルを提案し、これによりITER計画に対する局所偏光測定の適用可能性を解析する。約0.3 mの局所偏光測定の許容可能な空間分解能は、ITER計画で想定されるプラズマ密度（Ne = 10¹⁴〜10¹⁵ cm⁻³）よりも著しく高い密度（Ne = 10¹⁷ cm⁻³のオーダー）で達成可能であることが示される。
