Paper Abstract

A novel polarization-based fingerprint identification sensor is proposed in this paper. This sensor consists of an optoelectronic system where the enrollment process is recorded optically and the identification process is carried out digitally using the concept of fringe-adjusted joint transform correlation technique. In the optical part, a polarized coherent light beam is used to record spatially dependent response of the scattering medium of the fingerprint to provide detailed surface information, which is not accessible to mere intensity measurement. Both simulation and experimental results are presented to evaluate the performance of the proposed technique.
