Abstract[English]
The present invention relates to a system and a method for contactless measurement of the temperature of a portion (3') of an object (3) coated with a layer of a phosphor material from the zinc oxide family, by means of a light source (1) emitting in a wavelength range at least partially covering a range between 360 and 480 nm, and means for measuring a light intensity as a function of wavelength (5), covering at least one portion of the range of the light source (1), wherein a light intensity of the radiation scattered by the portion of the object is measured as a function of wavelength. Next, on the basis of the measurement of the light intensity as a function of wavelength, a value of at least one parameter is determined, and the temperature of the portion (3') of the object (3) is determined from the value of the parameter and a predetermined correspondence table.[French]
La présente invention concerne un système et un procédé pour une mesure sans contact de la température d'une portion (3') d'un objet (3) revêtue par une couche d'un matériau luminophore de la famille des oxydes de zinc Au moyen d'une source lumineuse (1) émettant dans une gamme de longueurs d'onde couvrant au moins partiellement une gamme comprise entre 360 et 480 nm et de moyens de mesure d'une intensité lumineuse en fonction de la longueur d'onde (5) couvrant au moins une partie de la gamme de la source lumineuse (1), on mesure une intensité lumineuse en fonction de la longueur d'onde d'un rayonnement diffusé par la portion de l'objet. Puis, à partir de la mesure de l'intensité lumineuse en fonction de la longueur d'onde, on détermine une valeur d'au moins un paramètre, et on détermine la température de la portion (3') de l'objet (3) à partir de la valeur du paramètre et d'une table de correspondance prédéterminée.
