CA 2339164

The invention relates to an assembly for detecting the superficial structures of fingers (3), palms, or other skin parts which are placed on an image scanning surface (1). The image scanning surface (1) is configured on a scanning prism (2); an illuminating beam (5) is directed towards the image scanning surface (1) inside the scanning prism (2) and the light reflected by the latter is projected onto the receiving surface (11) of an optoelectronic detection unit (12). According to the invention, in an assembly of this type, a section of the illuminating beam (5.1, 5.2) or a separate illuminating beam is directed towards fixed reference structures (13) and from these onto the receiving surface (11). Separate partial areas (C, C1, C2) of the receiving surface (11) are reserved for the detection of the surface structures and for the detection of the reference structures (13).

L'invention concerne un dispositif pour détecter des structures superficielles de doigts (3), des surfaces intérieures de mains ou d'autres parties de la peau, posés sur une surface de balayage d'image (1). La surface de balayage d'image (1) est formée sur un prisme de balayage (2) à l'intérieur duquel un trajet de rayonnement d'éclairage (5) est dirigé sur la surface de balayage d'image (1), la lumière réfléchie par cette dernière arrivant sur la surface de réception (11) d'un dispositif de détection optoélectronique (12). Selon l'invention, une partie du trajet de rayonnement d'éclairage (5.1, 5.2) ou un trajet de rayonnement d'éclairage séparé sont dirigés sur des structures de référence fixes (13) puis, à partir de ces dernières, sur les surfaces de réception (11). Des zones partielles séparées (C, C¿1?, C¿2?) de la surface de réception (11) sont réservées à la détection des structures superficielles et à la détection des structures de référence (13).
