| Abstract: | In this paper, a recognition method based on phase-encoding is proposed. In the method when a phase-encoded filter is applied to an optical correlator, several separable correlation responses are abtained simultaneously. Binarized responses can be used as recognition codes, This method greatly improves the recognition capability of an optical correlation system. |
