Abstract

L'invention concerne un dispositif de visualisation in-situ d'éléments particulaires en déplacement dans un fluide turbide, comprenant :- des moyens de capture d'image (1),- des moyens d'éclairage (2) configurés pour envoyer une lumière d'excitation sur une surface à analyser (3) dudit fluide,ledit dispositif étant remarquable en ce que lesdits moyens de capture d'image (1) et lesdits moyens d'éclairage (2) sont disposés dans un milieu séparé du fluide turbide par au moins une paroi transparente et en ce que les moyens d'éclairage (2) sont constitués d'un ensemble de sources lumineuses ponctuelles disposées de manière sensiblement symétrique par rapport à un point central.The invention relates to a device for in-situ visualization of particulate elements moving in a turbid fluid, comprising: - image-capturing means (1), - lighting means (2) configured to send a light excitation device on a surface to be analyzed (3) of said fluid, said device being remarkable in that said image-capturing means (1) and said lighting means (2) are arranged in a medium separated from the turbid fluid by at least one transparent wall and in that the lighting means (2) consist of a set of point light sources arranged substantially symmetrically with respect to a central point.
