B編}, month = {Jun}, note = {application/pdf, A novel polarized-type phase Doppler method is proposed for simultaneous measurements of particle size, velocity and refractive index on the basis of. the phases of two polarized Doppler beat signals in a single scattering direction. Light scattered by a moving particle in a certain direction is divided into two rays, which are then detected with different polarization angles to transmit dominantly reflected or refracted rays. Signal phases of these two rays are measured with respect to the phase of beat signal obtained by the reference detector. The particle diameter can be determined from the phase of reflected ray, whereas the particle refractive index can be obtained from the phase ratio of reflected and refracted rays. We carried out numerical computations and experiments to confirm the usefulness of the proposed method for simultaneous measurements of the particle size and refractive index.}, pages = {1422--1429}, title = {偏光型位相ドップラー法を用いた粒子径と屈折率の同時計測}, volume = {67}, year = {2001}, yomi = {ヨコイ, ナオミチ and アイズ, ヨシヒサ and ミシナ, ヒロミチ} }
