in this paper, we present a hybrid photoelectric joint transform correlator,where electrically addressed liquid crystal display(EALCD) is used as spatial light modulator in this system ; The CCD matrix camera as square law detection records joint transform power spectrum in spectrum space. Through optical Fourier transform, we can gain correlation signal; the target can be recognized by the correlation signal, so we can determine the orientation of the target .the strongpoint is the operation speed is ver...
