Optical Fingerprint Identification by Binary Joint Transform Correlation.

Abstract

We describe an optical fingerprint identification system that optically reads a latent fingerprint for correlation using a binary joint transform correlator. The fingerprint is read using the total internal reflection property of a prism. The system was built, using a guide to keep the finger in the same orientation each time. The purpose of research effort in optical signal processing is to develop techniques leading to systems that optically process data at very high rates of speed, preferably with smaller volume and lower power requirements. Image processing systems based on the joint Fourier transform technique (JTC) have been shown to have good performance.
