Title (EN) DEVICE AND METHOD FOR DETECTING PARTICLES
(FR) DISPOSITIF ET PROCÉDÉ DE DÉTECTION DE PARTICULES
(DE) VORRICHTUNG UND VERFAHREN ZUR DETEKTION VON PARTIKELN
Abstract:
(EN) The invention relates to a device (10) and a method for detecting particles (20), comprising at least one light source (12) and at least one detector (14) for detecting light. At least one medium (16) can be transilluminated by light provided by the light source (12) and has a deposition surface (18) for the particles (20). The detector (14) is designed to detect light penetrating the medium (16) and reflected by the particles (20) deposited on the deposition surface (18).
(FR) L'invention concerne un dispositif (10) ainsi qu'un procédé de détection de particules (20), le dispositif comprenant au moins une source de lumière (12) et au moins un détecteur (14) servant à détecter la lumière, au moins un milieu (16) pouvant être traversé par la lumière émise par la source de lumière (12) et présentant une surface de dépôt (18) pour les particules (20), le détecteur (14) étant conçu pour détecter la lumière qui est réfléchie par les particules (20) déposées sur la surface de dépôt (18) et qui traverse le milieu (16).
(DE) Die Erfindung betrifft eine Vorrichtung (10) sowie ein Ver- fahren zur Detektion von Partikeln (20), mit wenigstens einer Lichtquelle (12), und mit wenigstens einem Detektor (14) zum Erfassen von Licht, wobei wenigstens ein Medium (16) von von der Lichtquelle (12) bereitgestelltem Licht durchleuchtbar ist, welches eine Ablagerungsoberfläche (18) für die Partikel (20) aufweist, wobei der Detektor (14) dazu ausgebildet ist, von den auf der Ablagerungsoberfläche (18) abgelagerten Par- tikeln (20) reflektiertes und das Medium (16) durchdringendes Licht zu erfassen.
