Abstract

L'invention concerne un système de détection de particules comprenant un élément optique réfléchissant qui comporte une surface incurvée pour détecter une lumière diffusée selon un angle élevé, générée par une particule dans une substance liquide lorsqu'un faisceau laser rencontre ladite particule. Lorsque les particules traversent le faisceau laser, la lumière est diffusée dans toutes les directions et est décrite par la théorie de diffusion MIE pour les particules dont la taille est approximativement égale ou supérieure à la longueur d'onde de la lumière, ou par la théorie de diffusion de Rayleigh lorsque la taille des particules est inférieure à la longueur d'onde de la lumière. L'utilisation d'un élément optique réfléchissant permet de détecter la lumière diffusée à des d'angles supérieurs aux angles pouvant normalement être obtenus.
