Abstract

Combining the concepts of phase-only filtering and multiple-exposure holography, we propose a method for making a phase-only composite filter using a plane reference wave as the carrier. We used this filter for the optical recognition of four kinds of hardware items, and the results of a computer simulation are presented. The characteristics and possible applications of this correlation recognition method are discussed.
