Paper Abstract

Combining phase-only filtering with the idea of multiple exposure hologram, we propose a method to make a phase-only synthetic filter for multiobject recognition. When the filter is used in an optical correlation, several correlation responses appear on the output plane. According to the height of the correlation peak, we can easily recognize each of the multiobjects. The results of computer simulation are presented. The characteristic and application prospects of this correlation recognition method are discussed.
