    • Abstract
  • In order to control the voltage of each electrode of a liquid-crystal-based phased array independently,based on field programmable gate array,the voltage of electrodes of the liquid-crystal-based phased array was driven to regulate phase distribution of electrodes.Analytical and experimental results show that periodic phase distribution of the electrodes can modulate the phase of an optical beam,i.e.,scan can be accomplished.This conclusion is helpful for adjusting phase of the electrodes of a liquid-crystal-based phased array.
