Abstract

LA PRESENTE INVENTION CONCERNE UN APPAREIL D'IDENTIFICATION ET DE TRAITEMENT DE L'IMAGE D'UN DOIGT. CET APPAREIL EST CARACTERISE EN CE QU'IL COMPREND UNE PLAQUE PRESENTANT UNE SURFACE ANTERIEURE ADAPTEE DE MANIERE A RECEVOIR UN FAISCEAU DE LUMIERE COLLIMATE OU ALIGNE ET UNE SURFACE POSTERIEURE ADAPTEE DE MANIERE A RECEVOIR SUR ELLE UN DOIGT, CETTE PLAQUE COMPORTANT UN SUBSTRAT TRANSPARENT ET UNE COUCHE TRANSPARENTE ELASTIQUE ET COMPRESSIBLE, AYANT UNE EPAISSEUR SUFFISANTE ET UNE COMPRESSIBILITE SUFFISANTE TELLES QUE LES FORCES TRANSMISES PAR LES CRETES DU DOIGT APPUYE SUR LA COUCHE COMPRESSIBLE PROVOQUENTAISEMENT UNE DEFORMATION DE LADITE COUCHE COMPRESSIBLE DANS LES ZONES SITUEES EN DESSOUS DES CRETES DU DOIGT APPUYE. APPLICABLE A L'IDENTIFICATION D'EMPREINTES DIGITALES.THE PRESENT INVENTION CONCERNS AN APPARATUS FOR IDENTIFYING AND PROCESSING THE IMAGE OF A FINGER. THIS APPARATUS IS CHARACTERIZED IN THAT IT INCLUDES A PLATE HAVING A FRONT SURFACE SUITABLE TO RECEIVE A COLLIMATE OR ALIGNED BEAM OF LIGHT AND A BACK SURFACE SUITABLE TO RECEIVE A FINGER ON IT, CARRYING A SUBSTRATE ON IT ELASTIC AND COMPRESSIBLE TRANSPARENT LAYER, HAVING SUFFICIENT THICKNESS AND SUFFICIENT COMPRESSIBILITY SUCH AS THE FORCES TRANSMITTED BY THE FINGER CREES PRESSED ON THE COMPRESSIBLE LAYER CAUSING A DEFORMATION OF THE SUFFICIENT LAYER COMPRESSIBLE ZONES IN THE DOES SQUIT. APPLICABLE TO THE IDENTIFICATION OF FINGERPRINTS.
