Title
(EN) PARTICLE MONITORING
(FR) SURVEILLANCE DE PARTICULES
Abstract
(EN)
A particle monitoring system may include a volume for containing a fluid in which particles are suspended, a photosensitive layer, a light encoding layer sandwiched between the volume and the photosensitive layer and electrodes to apply an electric field to the fluid within the volume and proximate the photosensitive layer.
(FR)
La présente invention concerne un système de surveillance de particules qui peut comprendre un volume destiné à contenir un fluide dans lequel des particules sont en suspension, une couche photosensible, une couche de codage de lumière prise en sandwich entre le volume et la couche photosensible et des électrodes pour appliquer un champ électrique au fluide à l'intérieur du volume et à proximité de la couche photosensible.
