Title
(EN) INDUSTRIALLY ROBUST NON-CONTACT COLOR MEASUREMENT DEVICE
(FR) DISPOSITIF DE MESURE SANS CONTACT DE COULEURS DE ROBUSTESSE INDUSTRIELLE
Abstract
(EN)
A color measurement device designed for use at various stages of an industrial process is provided. The device offers enhanced insensitivity to ambient light, measurement depth variations, and/or ambient or environmental temperature variations. The device may be embodied as an LED-based, non-contact color measurement spectrophotometer. Over- illumination in full-spectrum of the target object facilitates effective color measurements over varying depths of view. Collected light is measured at discrete wavelengths across the entire visual spectrum. The hardened, rugged design and packaging of the measurement device allows color measurement to be performed at various stages of industrial processes wherein the device can add value by enabling enhanced detection of color errors.

L'invention porte sur un dispositif de mesure de couleurs pouvant s'utiliser à différentes étapes d'un processus industriel. Le dispositif présente une insensibilité accrue à la lumière ambiante, aux variations de la profondeur de mesure ou aux variations de la température ambiante. Il peut se présenter en tant que spectrophotomètre de mesure de couleurs à DEL sans contact. Le suréclairage sur la totalité du spectre de l'objet cible facilite les mesure à des profondeur de vue variables. La lumière recueillie est mesurée pour des longueurs d'onde discrètes sur l'ensemble du spectre visible. La conception et l'habillage robustes du dispositif permettent de l'utiliser à différentes étapes d'un processus industriel où il apporte une valeur ajoutée par la détection des erreurs de couleur.
