Abstract
The invention relates to a fingerprint scanning system and a method of scanning a fingerprint. A system according to the invention may have (a) an imaging surface capable of receiving a finger, (b) a rotatable disk, the disk having a pivot-location about which the disk rotates, (c) an ultrasound transducer joined to the disk and capable of providing information corresponding to a fingerprint of the finger, (d) a disk driver capable of rotating the disk in order to cause the transducer to move along a substantially circular path, (e) a linear driver capable of moving the pivot-location linearly, (f) a measurer capable of measuring linear positions of the pivot-location and arcuate positions of the transducer; and (g) a coupler capable of producing sets of coupled information, each set comprising one linear position of the pivot-location, one arcuate position of the transducer and information produced from the transducer at the pivot-location and arcuate position.
