A fingerprint acquisition device comprising, a space for receiving a finger of a user, a light source configured to emit a illumination light illuminating the space, a camera configured to acquire an image of a fingerprint of the finger, when the finger is received in the space, and, a polarization system configured to polarize the illumination light before the illumination light reaches the space and after the illumination light has passed through the space, and to polarize an ambient light emanating from outside the device and propagating towards the camera, before the ambient light reaches the space, and to polarize the ambient light after the ambient light has passed through the space.

Fingerprint acquisition device

The present invention relates to a terminal comprising a main body having an upper surface that is substantially horizontal; a tower extending substantially vertically from said main body, so as to define an acquisition volume delimited by said upper surface and the tower; optical acquisition means arranged within the main body so as to be able to acquire an image of a biometric print placed within the acquisition volume facing the upper surface; a user interface arranged within the tower; wherein the tower has a cavity, and the user interface comprises a screen arranged at the bottom of the cavity and a semi-reflective plate closing the cavity so as to provide the optical illusion that said screen is floating within the acquisition volume. The present invention further relates to a method for acquiring an image of a biometric print by means of the terminal.

Biometric terminal, in particular for access control

A biometric capture device having an optical block integrating an acquisition surface, an optical acquisition system arranged so that a first light ray propagating, outside the optical block, along an optical axis of the said optical acquisition system forms at the level of the acquisition surface, an angle with respect to a normal to the acquisition surface of a value greater than a critical angle depending on the refractive indices of the optical block and of the air, the optical system also being arranged so that the optical axis forms an angle with respect to a normal to the exit face less than said critical angle, an illumination system configured to provide illumination of the acquisition surface, the illumination system generating a light beam defined by an illumination axis, a second light ray propagating along the illumination axis out of the optical block.

Biometric capture device

A biometric inspection device including a housing provided with an acquisition interface, the device including an optical sensor for acquiring at least one image of a portion of the body of a candidate for inspection appearing before the acquisition interface. The optical sensor is configured so that the image also covers an internal zone of the housing situated outside the acquisition interface.

Biometric inspection device with integrity verification, and an associated method

Method for detecting the presence of a body part carrying an imprint on an imprint sensor comprising a transparent face on which a body part must be placed, an image sensor, situated opposite the transparent face, able to acquire an image of an imprint, a light source for illuminating a body part placed on the transparent face. The method comprises: switching on the light source; acquiring a multicomponent image with the image sensor, each color component of the multicomponent sensor corresponding to a predefined wavelength range; obtaining, for each color component of said multicomponent image, information representing a signal generated by said image sensor for said color component; comparing said representative items of information with each other and detecting the presence of a body part according to the result of the comparison.
