Abstract
The detection efficiencies for the nonzero-order joint transform corre lator (NOJTC) and the conventional joint transform correlator (CJTC) a re evaluated. We show that the NOJTC outperforms the CJTC under both t he noiseless and noisy conditions, due to the high diffraction efficie ncy (DE) of the NOJTC. We also show that false alarms created by inter target modulation can indeed be avoided using the NOJTC. (C) 1998 Soci ety of Photo-Optical Instrumentation Engineers. [S0091-3286(98)01501-3 ].
