Fingerprint detection using sweep-type imager with optoelectronic speed sensor

In a method and an arrangement for detecting skinprints, in particular fingerprints, it is provided that at least one strip sensor comprising at least one elongate narrow sensor line detects the structure of the fingertip when the fingertip passes over the strip sensor, that at least one optoelectronic speed sensor continuously determines the finger movement, that the fingertip is moved over at least one optoelectronic speed sensor and the strip sensor, and that the determined finger movement is used to correct an image of the finger structure that has been distorted as a result of non-uniform movement. Preferably, the speed sensor evaluates the Doppler shift of a modulation of the modulated laser light reflected at the moved finger surface.
