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.
