Abstract

L'invention concerne un système de détection de particules contenues dans un fluide (2), comprenant : Un conduit (1) agencé pour faire circuler de l'amont vers l'aval, un flux dudit fluide, Des moyens d'injection dudit fluide (2) dans ledit conduit, agencés pour créer ledit flux dans ledit conduit (1) suivant au moins une direction d'injection, Une source lumineuse (5), - Une caméra (7) présentant un axe optique, Ledit conduit comportant au moins un tronçon intermédiaire (11) à section transparente destiné à être traversé par ledit flux suivant au moins une direction d'injection, Ladite source lumineuse est configurée pour générer une nappe lumineuse à travers ledit tronçon intermédiaire (11), formant au moins une section d'éclairement (S) dans ledit conduit qui est perpendiculaire à ladite direction d'injection, Ladite caméra (7) est agencée pour positionner son axe optique suivant une direction parallèle à ladite direction d'injection.
