Abstract:
1. A system for identifying an individual by recording a body imprint, in a region of the body of the individual, the system comprising means of optically capturing an image of a body imprint, from said region of the individual's body, means of optically capturing an image of at least a portion of the venous network in said region of the individual's body and underlying said body imprint, said system comprising two lighting means capable of emitting two light beams, respectively, containing two light radiations having two separate wavelengths, respectively, and sensing means capable of capturing said images in connection with said respective wavelengths, the system further comprising: a prismatic optical element having a large face at least a portion of which consists of a region for apposition of a body region of an individual, first lighting means capable of emitting a first light radiation having a first wavelength and being arranged opposite a first inclined lateral face of said prismatic optical element, such that said first radiation emitted by said first lighting means passes through said prismatic optical element in order to arrive at said apposition region at an angle of incidence capable of total reflection, a first sensor sensitive to said first radiation being arranged opposite a second inclined lateral face of said prismatic optical element opposite said first inclined lateral face, so as to receive said first radiation reflected by said large face of said prismatic optical element and carrying an image of the body imprint when a region of an individual's body is applied to said apposition region, second lighting means capable of emitting a second light radiation having a second wavelength being arranged opposite a small face of the prismatic optical element such that said second radiation emitted by said second lighting means passes through said prismatic optical element in order to arrive at said apposition region, which is substantially perpendicular thereto and capable of penetrating into the region of the body when a region of an individual's body is applied to said apposition region, and said second sensor sensitive to said second radiation being arranged opposite said small face of said prismatic optical element so as to receive said second reflected radiation carrying an image of at least a portion of the underlying venous network, when a region of an individual's body is applied to said apposition region.
