Abstract:
1. A biometric sensor system for generating a three-dimensional representation of a portion of a finger, the finger comprising a three-dimensional structure including a surface tissue layer and a subsurface tissue layer, the biometric sensor comprising: a platen configured to receive the finger; a first transducer arranged about the platen, configured to scan at least a portion of the finger by receiving ultrasound waves after the ultrasound waves reflect off of the finger, and further configured to output signals based upon the received ultrasound waves; a drive system configured to motivate the first transducer arcuately about a z-axis substantially parallel to the length of the finger to be scanned; a controller configured to control the motion of the drive system; and a software module configured to receive a form of the signals from the first transducer and to compose the form of the signals into a three-dimensional representation of at least a portion of the surface tissue layer of the finger wherein the software module is further configured to compose the form of the signals into a three-dimensional representation of at least, a portion of a subsurface tissue layer of the finger.
