Automated Identification and Analysis of Fingerprints by Interferometry

CODEN: JFSCAS

Abstract

The intricate line pattern of epidermal ridges in a fingerprint can be transformed into a characteristic interferogram of the moiré type by superimposing a centrosymmetric reference pattern. The interferogram is then dissected automatically into an array of cells whose optical densities are translated into a sequence of binary digits. By this procedure, fingerprints are easily read, filed, and transmitted as well as analyzed, identified, and matched by microcomputers.
