Paper Abstract

We present a design procedure and atrial fabrication of a new 2D light source module composed of a vertical cavity surface emitting laser (VCSEL) array and a multi-level zone plate (MLZP) array as collimate lens. Furthermore, its application to an optical parallel correlator for facial recognition is also exhibited. The size is reduced by one-fifth and the throughput time of MLCOPaC with twelve parallel channels module is also, improved to record 19 faces which is 3 times faster than the second-generation compact parallel correlaor. By experimentally evaluating the system through one-to-one correlation using 300 database of front facial images, two kinds of error; False Match Rate 1.7% and False Non-Match Rate 1%, were obtained. Consequently, our system proved robust as applications to a security apparatus such as PC log-in entry control for network systems.
