Abstract

Procédé et appareil de détection d’écran solaire sur de la peau ayant diverses couches de produit cosmétique La présente invention concerne un appareil (1) de détection d’un écran solaire, comprenant : une source de lumière (2) ; un filtre de passage de lumière ultraviolette (4); un capteur de lumière visible (6) ; et un polariseur (8) et une cible d’irradiation (10), dans lequel le filtre de passage de lumière ultraviolette est configuré pour laisser passer de la lumière ayant une longueur d’onde dans une gamme de lumière ultraviolette, dans lequel la cible d’irradiation inclut une substance émettant de la lumière fluorescente en réponse à l’irradiation de lumière, dans lequel le polariseur est configuré pour bloquer au moins une partie de la lumière émise depuis la source de lumière et réfléchie par la cible d’irradiation, et dans lequel le capteur de lumière visible est configuré pour déterminer une intensité de la lumière fluorescente passant à travers le polariseur. Figure pour l’abrégé : figure 1Method and apparatus for detecting sunscreen on skin having various layers of cosmetic product The present invention relates to an apparatus (1) for detecting a sunscreen, comprising: a light source (2); an ultraviolet light passing filter (4); a visible light sensor (6); and a polarizer (8) and an irradiation target (10), wherein the ultraviolet light passing filter is configured to pass light having a wavelength in an ultraviolet light range, wherein the irradiation target includes a substance emitting fluorescent light in response to the light irradiation, wherein the polarizer is configured to block at least a portion of light emitted from the light source and reflected by the irradiation target, and wherein the visible light sensor is configured to determine an intensity of the fluorescent light passing through the polarizer.
