Title
(DE) BESTIMMUNG EINES DEHNUNGSGRADES VON HAAR MIT EINEM NIR-SENSOR
(EN) DETERMINATION OF A DEGREE OF ELONGATION OF HAIR USING A NIR SENSOR
(FR) DÉTERMINATION D'UN TAUX D'ALLONGEMENT DU CHEVEU AVEC UN CAPTEUR PROCHE INFRAROUGE
Abstract
(DE) Es ist eine Anordnung (100) zum Bestimmen eines Dehnungsgrades von Haar angegeben. Die Anordnung enthält eine Erfassungseinheit (110) zum Erfassen von Haarmerkmalen und eine Auswerteeinheit (120) zum Auswerten der erfassten Haarmerkmale und zum Ermitteln des Dehnungsgrades von Haar basierend auf den erfassten Haarmerkmalen. Die Erfassungseinheit (110) enthält einen Nahinfrarotsensor, NIRS, und ist ausgeführt, eine Haarprobe mit elektromagnetischen Wellen im Infrarotbereich zu bestrahlen und einen Absorptionsgrad der Haarprobe in einem Wellenlängenbereich von 800 bis 2500 nm zu erfassen. Die Erfassungseinheit (110) ist ausgeführt, ein Absorptionsspektrum der Haarprobe in dem Wellenlängenbereich von 800 bis 2500 nm zu generieren und der Auswerteeinheit (120) bereitzustellen und die Auswerteeinheit (120) ist ausgeführt, das generierte Absorptionsspektrum mit einem Kalibriermodell abzugleichen und einen Dehnungsgrad der Haarprobe basierend auf dem Absorptionsspektrum und dem Kalibriermodell zu ermitteln.
(EN) The invention relates to an arrangement (100) for determining a degree of elongation of hair. The arrangement contains a detection unit (110) for detecting hair characteristics and an evaluation unit (120) for evaluating the detected hair characteristics and for determining the degree of elongation of hair based on the detected hair characteristics. The detection unit (110) contains a near-infrared sensor, NIRS, and is designed to irradiate a hair sample with electromagnetic waves in the infrared range and to detect a degree of absorption of the hair sample in a wavelength range of between 800 and 2500 nm. The detection unit (110) is designed to generate an absorption spectrum of the hair sample in the wavelength range of between 800 and 2500 nm and to supply it to the evaluation unit (120), and the evaluation unit (120) is designed to compare the generated absorption spectrum with a calibration model and to determine a degree of elongation of the hair sample based on the absorption spectrum and the calibration model.
(FR) L’invention concerne un ensemble (100) permettant de déterminer un taux d'allongement du cheveu. L'ensemble contient une unité de détection (110) destinée à détecter des caractéristiques capillaires et une unité d'évaluation (120) destinée à évaluer les caractéristiques capillaires détectées et à déterminer le taux d'allongement du cheveu sur la base des caractéristiques capillaires détectées. L'unité de détection (110) contient un capteur proche infrarouge, NIRS, et est conçue de manière à exposer un échantillon capillaire à l'action des ondes électromagnétiques situées dans la plage des infrarouges et à détecter un degré d'absorption de l'échantillon capillaire dans une plage de longueurs d'ondes comprise entre 800 et 2500 nm. L'unité de détection (110) est conçue de sorte à générer un spectre d'absorption de l'échantillon capillaire dans la plage de longueurs d'ondes comprise entre 800 et 2500 nm et à le fournir à l'unité d'évaluation (120) et ladite unité d'évaluation (120) est conçue de sorte à comparer le spectre d'absorption généré avec un modèle d'étalonnage et à déterminer un taux d'allongement du cheveu de l'échantillon capillaire, sur la base du spectre d'absorption et du modèle d'étalonnage.
