A simple method of removing the zero order in a joint transform power spectrum, i.e., using the nonzero-order joint transform power spectrum (N0JTPS), is discussed. We show that the nonzero-order joint transform correlator (N0JTC) performs better than the conventional joint transform correlator (CJTC). In short, the N0JTC offers high detection efficiency, better input pixel utilization, and avoidance of false alarms due to multitarget intermodulation. Simulated and experimental demonstrations are provided.
