Abstract
We present a VanderLugt-type optical phase-only correlator that uses t he currently available liquid-crystal television. Theoretical and expe rimental results show that phase mismatching and phase and amplitude c ross coupling of the liquid-crystal television can reduce the peak int ensity to approximately 60%-70%. The imperfect phase-only filter yield s on-axis correlation with high light efficiency and utilizes all the available space-bandwidth product of the liquid-crystal television.
