    摘要: An apparatus for direct optical recording of skin prints has a display below the placement surface and a light guide layer below the display. The light guide layer has light in-coupling at a narrow side and light out-coupling structures in the surface. By means of angles ε of the light out-coupling structures and differences in the refractive indices of the neighboring layers, a directed coupling out of light occurs in the direction of the placement surface causing a total internal reflection at the placement surface. The display has a transparency of at least 1% of the coupled out light. A first and second adhesion layers are between the display and the light guide layer and between the light guide layer and the sensor layer. The refractive indices of the adhesion layers are at least 1% to 30% lower than those of light guide layer, the display and the sensor layer.

    摘要: 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.

    摘要: 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.

    摘要: A method for monitoring a mobile input device with a screen on which information can be displayed in a first pixel raster of image elements and which comprises a flat optical fingerprint reader and a second pixel raster of light-sensitive sensor elements. A fingerprint and fingerprint characteristics, comprising position of the finger on the screen are detected. The sensor elements detect the light intensity incident on them. The intensity levels are assembled into a static pattern of the fingerprint. The combination of the static pattern and the fingerprint characteristics are compared with a database. If the combination is in the database, a check is carried out whether an action is associated with this combination, which is then carried out, or whether no action is associated with this combination, whereupon a first standard action is carried out. If the combination is not stored, a second standard action is carried out.

    摘要: An apparatus for direct optical capture of security-relevant objects such as at least skin prints and documents produces a contrast between skin ridges and skin valleys in direct optical sensors for capturing skin prints in the range of contrast of conventional systems with frustrated total internal reflection. A contrast aperture layer is provided with one contrast aperture associated with each light-sensitive element of the sensor layer. The associated contrast aperture is arranged at a distance above the light-sensitive element and has a surface area at least as large as an active region of the light-sensitive element). The contrast aperture is arranged at a distance above the light-sensitive element such that at least 60% of the active region is covered. The illumination layer has a plurality of point light sources which emit in direction of the placement surface in an angular area limited for preventing total internal reflection.

    摘要: 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.

    摘要: 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.
