Abstract
An ultrasonic finger print authentication system that generates a three-dimensional representation of a fingerprint. High frequency sound waves are used as a medium for imaging finer details of the patterns on a fingertip, including the ridge and valley formations. Multiple frequencies and beam-forming are used to quickly map the ridges. Acoustic resonance is used to determine the depths of the intervening valleys.
