To estimate the complex refractive indices and the size distributions of aerosols and hydrosols from light scattering measurements, we present a data processing technique using both inversion and library methods. Extensive numerical simulations have shown that the true values of complex refractive index and size distribution are retrieved fairly well when this method is applied to measurements of polarization components of scattered radiation parallel and perpendicular to the scattering plane.
光散乱測定によって,エアロゾルやハイドロゾルの複素屈折率と粒径分布を評価するために,インバージョン法とライブラリー・法を同時に使うデータ解析法を提案する。詳細な数値実験の結果,この方法を散乱面に水平および垂直な散乱光の偏光成分の測定に適用すると,複素屈折率と粒径分布の真値を良く推定できることが明らかになった。
