Abstract: A device and method for non-contact optical imaging of a selected surface area of a user's hand, wherein the surface area is actively guided in a non-contact manner into a target position with respect to an image capture unit. For this purpose, the device has a frame in which the hand is inserted, assuming an actual position, roughly related to the target position. In addition, the device contains at least one active means for localizing the respective actual position and an output unit via which feedback is given to the user and the user iteratively guides the surface area into the target position. Advantageously, the device and method are suitable for distinguishing a natural hand from an artificial hand.

Abstract: A device for displaying information and for the contact-based, simultaneous capture of impressions of a plurality of blood-perfused skin regions of human autopodia, including: a placement surface for placing the autopodia, a display unit which is arranged below the placement surface and which has at least partially transparent display elements which are arranged in grid form and are individually controllable by a control unit, the display elements having display pixels which emit light in a direction of the placement surface. The device also includes optical sensor pixels which detect light incident on the sensor pixels. The sensor pixels may be arranged in a sensor layer arranged under the display unit viewed from direction of the contacting skin region or may be arranged in the display unit between the display elements. A cavity filter for angle selection is arranged in front of the optical sensor pixels.

Abstract: A device for displaying information and for capture of prints of a plurality of skin areas of human autopodia by means of reflection, comprising: a placement surface for applying the autopodia, a touch-sensitive layer, an LC unit with pixels arranged which are individually controllable by a control unit, an illumination unit with a transparent light-guide-layer body, first and second illumination means, and an optical sensor layer with sensors below the light-guide-layer body. The first illumination means emits diffuse light in a first wavelength range, and the second emits directed light in a predefined angular range and in a second wavelength range. The sensor elements are sensitive to light of the second wavelength range. The pixels are switchable between a state which is transparent to the diffuse light and directed light and a state which is opaque to the diffuse light, and are illuminated by the diffuse light for displaying information.

Abstract: A display with integrated matrix sensor for the optical recording of the papillary structure of at least one finger (F), in which an angular diaphragm with an aperture is arranged in each instance in front of the individual sensor elements of the matrix sensor, which aperture is offset relative to the sensor element in each instance in an offset direction (RV). Because of different dimensioning of the apertures and/or different offset directions (RV), the acceptance angle of the sensor elements of the matrix sensor is also influenced in direction orthogonal to the offset directions (RV) so that the display is suitable for making a recording having an isotropic and high contrast. The invention is also directed to a method by which, using a display according to the invention with integrated matrix sensor, an initial recording is transformed into a corrected recording having an at least approximately isotropic and high contrast.

Abstract: A device for direct optical recording of skin prints offers recording of human skin prints for personal identification permitting a display layer directly below the placement surface. A light guide layer arranged below the sensor layer has at least one LED at a narrow side and light out-coupling structures which, by means of an inclination angle c and differences in the refractive indices relative to neighboring layers, permit a directed coupling out of light at a defined angle which results in total internal reflection at the placement surface at the air interface and with a small divergence angle range of ?+/?15°. A first adhesion layer between cover layer and sensor layer and a second adhesion layer between sensor layer and light guide layer are provided, the refractive indices of which are 1% to 30% lower than the refractive indices of light guide layer and sensor layer.
