【Abstract】 The basic principle of joint transform is described. Joint transformis realized by suing the polaried modulation charac-teristics of LCLV.As areal-time recording element,LCLV may improve the power spectrum of objectsto get better correlation output. Anew method for real-time optical correlationis given. The results are consistent with the theory analysis.更多还原
