Abstract
(EN) An optical detector (110) for determining at least one property (220) of at least one substance (112), comprising at least one first optical sensor (114) comprising at least one first sensor layer (116) and at least one second optical sensor (120) comprising at least one second sensor layer (122), spaced apart from each other in a manner that a volume (132) between the first and second optical sensors is designated for receiving the at least one substance, at least two illumination sources (128, 128', 128") providing differently, periodically modulated first illumination light (118) for illuminating the first optical sensor, and at least one evaluation unit (136) for generating at least one item of information about at least one properly of the at least one substance; wherein the at least one first optical sensor is configured to transmit a share of the first illumination light into the volume; and related method
(FR) L'invention concerne un détecteur optique (110) destiné à déterminer au moins une propriété (220) d'au moins une substance (112), comprenant au moins un premier capteur optique (114) constitué d'au moins une première couche de capteur (116) et au moins un second capteur optique (120) constitué d'au moins une seconde couche de capteur (122), espacés l'un de l'autre, de telle sorte qu'un volume (132) entre le premier et le second capteur optique est destiné à recevoir ladite au moins une substance, au moins deux sources d'éclairage (128, 128′, 128″) fournissant une première lumière d'éclairage (118) modulée différemment et périodiquement pour éclairer le premier capteur optique, et au moins une unité d'évaluation (136) pour générer au moins une information sur au moins une caractéristique de ladite au moins une substance ; ledit au moins un premier capteur optique étant configuré pour transmettre une part de la première lumière d'illumination dans le volume ; et procédé associé.
