Abstract

A digital-optical hybrid processing system is successfully applied to perform real-time 3-D distorted invariant correlation with projection Synthetic Discriminant Function Matched Spatial Filtering (pSDF-MSF) technique. The pSDF-MSF filter is produced and used to perform rotation scale and shift simultaneously invariant correlation and optical pattern recognition (OPR). A sharp correlation peak with good S / N and improved light efficiency is obtained.
