Model of 2D optical correlator for fingerprint identification

This paper is devoted to the fingerprint identification problems and the experimental models of relevant optical setups. As published last year, some possibility of a fingerprint identification by means of 1D cut correlation has appeared. The first section of this paper deals with an improvement of our previous method based upon a 1D cut correlation. Originally a fingerprint photographic film record was used. Recently a fingerprint was displayed on a 2D hi-res LCD panel, SHARP. The second section of this paper is devoted to a comparative experimental verification of widely used JTC as a reference 2D correlation method. Finally, a set of experimental data for both techniques is presented.
