Optical correlator for industrial applications, quality control and target tracking

This paper describes a state‐of‐the‐art, commercially available optical correlator that has been used to perform industrial applications. The optical correlator can be used in many different applications including quality control, defect detection, target tracking and pattern recognition. The correlator has been designed to be rugged and is compatible with VGA and NTSC standards. The plug‐and‐play configuration makes it easy for engineers to test new industrial applications.
