Paper Abstract

We present a design procedure and trial fabrication of a new multi-light source module composed of vertical cavity surface emitting laser (VCSEL) array and multi-level zone plate (MLZP) array, and its applied to optical parallel correlator for facial recognition. The performance of the MLCOPaC with 20-channel parallel processing is experimentally demonstrated, and successful recognition rate for front facial images with 30 ms/face throughput and downsizing is proposed.
