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 (R). Because of different dimensioning of the apertures and/or different offset directions (R), the acceptance angle of the sensor elements of the matrix sensor is also influenced in direction orthogonal to the offset directions (R) 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.
