Abstract

Способ аспирационной оптической спектрометрии аэрозоля, при котором фокусируют излучение в счетном объеме, отличающийся тем, что поляризованное излучение направляют на область, задерживающую направленное поляризованное излучение, перед которой его экранируют, фокусируют направленное излучение в счетном объеме, находящемся перед экраном, а измеряют излучение за областью, задерживающей направленное поляризованное излучение и пропускающей излучение, рассеянное в счетном объеме, и определяют размер частицы дисперсной среды в счетном объеме по измеренному излучению.A method of optical aerosol aspiration optical spectrometry, in which radiation is focused in a countable volume, characterized in that the polarized radiation is directed to a region that delays directional polarized radiation, before which it is shielded, focused radiation is focused in a countable volume in front of the screen, and radiation is measured beyond the region , delaying the directed polarized radiation and transmitting radiation scattered in the countable volume, and determine the particle size of the dispersed medium in the counting measured radiation emission.
