Title (EN) METHOD AND DEVICE FOR OPTICALLY EXAMINING A LIQUID
(FR) PROCÉDÉ ET DISPOSITIF D’EXAMEN OPTIQUE D’UN LIQUIDE
(DE) VERFAHREN UND VORRICHTUNG ZUR OPTISCHEN UNTERSUCHUNG EINER FLÜSSIGKEIT
Abstract:
(EN) The invention relates to a method for optically examining a liquid (1) which contains particles (2), in particular the detergent solution in a washing machine. In the method, light (4) emitted by a light source (3) is coupled into the liquid (1). The light (5) reflected by the particles (2) is coupled out of the liquid (1), and at least some of the out-coupled reflected light (5) is received by a receiver (6). The light (5) received by the receiver (6) is subjected to a spectral analysis, in particular with respect to the color components contained therein, in particular in such a manner that the coloring of the liquid (1) is measured. For this purpose, the receiver (6) is a color sensor.
(FR) L’invention concerne un procédé d’examen optique d’un liquide (1) contenant des particules (2), en particulier de la lessive dans une machine à laver. Dans le procédé, de la lumière (4) émise par une source lumineuse (3) est injectée dans le liquide (1). La lumière (5), réfléchie par les particules (2), sort du liquide (1) et au moins une partie de la lumière réfléchie (5) en sortie est reçue par un récepteur (6). La lumière (5) reçue par le récepteur (6) est soumise à une analyse spectrale, notamment en ce qui concerne les composantes chromatiques qui y sont contenues, en particulier de manière à mesurer l’altération du liquide (1) en termes de couleur. Pour cela, le récepteur (6) est un capteur de couleurs.
(DE) Die Erfindung betrifft ein Verfahren zur optischen Untersuchung einer Partikel (2) enthaltenden Flüssigkeit (1), insbesondere der Waschlauge in einer Waschmaschine. Bei dem Verfahren wird von einer Lichtquelle (3) ausgesandtes Licht (4) in die Flüssigkeit (1) eingekoppelt. Das von den Partikeln (2) reflektierte Licht (5) wird aus der Flüssigkeit (1) ausgekoppelt und wenigstens ein Teil des ausgekoppelten, reflektierten Lichts (5) wird von einem Empfänger (6) aufgenommen. Das vom Empfänger (6) aufgenommene Licht (5) wird einer Spektralanalyse, insbesondere hinsichtlich der darin enthaltenen Farbanteile, unterzogen, insbesondere derart dass die Verfärbung der Flüssigkeit (1) gemessen wird. Zu diesem Zweck handelt es sich bei dem Empfänger (6) um einen Farbsensor.
