Title (EN) OPTICAL SOOT PARTICLE SENSOR FOR MOTOR VEHICLES
(FR) CAPTEUR DE PARTICULES DE SUIE OPTIQUE POUR VÉHICULES À MOTEUR
(DE) OPTISCHER RUßPARTIKELSENSOR FÜR KRAFTFAHRZEUGE
Abstract:
(EN) The invention relates to a soot particle sensor (16) comprising a laser module (18) which has a laser and comprising a detector (26) designed to detect thermal radiation (14). The soot particle sensor (16) is characterised in that the laser is designed to generate laser light (10) and in that the soot particle sensor (16) has an optical element (20) positioned in the optical path of the laser of the laser module (18), said element being designed to bundle laser light (10) emitted by the laser module (18) into a spot (22), and in that the detector (26) is positioned in the soot particle sensor (16) such that it detects radiation (14) emitted by the spot (22).
(FR) La présente invention concerne un capteur de particules de suie (16) optique avec un module laser (18) présentant un laser et avec un détecteur (26) conçu pour détecter le rayonnement thermique (14). Le capteur de particules de suie (16) est caractérisé en ce que le laser est conçu pour produire une lumière laser (10) et en ce que le capteur de particules de suie (16) présente un élément optique (20), agencé dans le trajet optique du laser du module laser (18), qui est conçu pour focaliser en un point (22) la lumière laser (10) sortant du module laser (18) et en ce que le détecteur (26) dans le capteur de particules de suie (16) est agencé pour détecter le faisceau (14) sortant du point (22).
(DE) Vorgestellt wird ein Rußpartikelsensor (16) mit einem einen Laser aufweisenden Lasermodul (18) und mit einem zur Detektion von Temperaturstrahlung (14) eingerichteten Detektor (26). Der Rußpartikelsensor (16) zeichnet sich dadurch aus, dass der Laser dazu eingerichtet ist, Laserlicht (10) erzeugen, und dass der Rußpartikelsensor (16) ein im Strahlengang des Lasers des Lasermoduls (18) angeordnetes optisches Element (20) aufweist, das dazu eingerichtet ist, von dem Lasermodul (18) ausgehendes Laserlicht (10) in einen Spot (22) zu bündeln, und dass der Detektor (26) im Rußpartikelsensor (16) so angeordnet ist, dass er vom Spot (22) ausgehende Strahlung (14) detektiert.
