Abstract
The invention may be embodied as a fingerprint scanner having an ultrasonic wave detector, a platen, an ultrasonic wave generator located between the detector and the platen. The invention may be embodied as a method of scanning a finger. One such method includes providing a platen, a detector and a generator, the generator being placed between the platen and the detector. A finger may be provided on the platen, and an ultrasound wave pulse may be sent from the generator toward the finger. The wave pulse may be reflected from the finger, and received at the detector. The received wave pulse may be used to produce an image of the finger.
