Abstract

L'invention a trait, d'une part, à un dispositif de lecture de résultat de test permettant de lire le résultat d'un test effectué au moyen d'une bande d'essai, le dispositif comprenant : une ou plusieurs sources de lumière émettant un faisceau incident sur au moins deux zones séparées dans l'espace de la bande d'essai; et un photodétecteur qui détecte la lumière émanant desdites zones. D'autre part, l'invention a trait à un dispositif de lecture de résultat de test permettant de lire le résultat d'un test effectué au moyen d'une bande d'essai, le dispositif comprenant : au moins une source de lumière émettant un faisceau incident sur une zone de la bande d'essai; et au moins deux photodétecteurs pouvant détecter une partie de la lumière émanant de la zone de la bande d'essai illuminée par la source de lumière.
