CA 2643371

A biodetector permits formation of an image of the inner face of the hand or of a finger of a user when the hand or the finger (101) is placed in front of an image-forming device (11), at a defined height (F). The height is adapted such that the biodetection image is sufficiently clear and is indicated to the user by means of a sign (40) projected onto the outer face of the hand or of the finger. Such a biodetector does not require the hand or finger to be applied to a support surface, and it permits intuitive and rapid use of the biodetector.

Un biodétecteur permet de former une image de la face interne de la main ou du doigt d'un utilisateur lorsque la main ou le doigt (101 ) est présentée devant un dispositif de formation d'image (11 ), à une hauteur déterminée (F). La hauteur est adaptée pour que l'image de biodétection présente une netteté suffisante, et est indiquée à l'utilisateur au moyen d'un signe (40) projeté sur la face externe de la main ou du doigt. Un tel biodétecteur ne nécessite pas d'appliquer la main ou le doigt sur une surface d'appui, et permet une utilisation intuitive et rapide du biodétecteur.
