DETECTION OF SAW FIELD OF PULSE COMPRESSOR BY LASER SCANNING PROBE

    Graphical Abstract
    • Abstract
  • In this article,the theory of acousto-optical interaction with metal strips on the crystal surface is presented.The original optical probe system is improved.The weak SAW field can be maped by new system.In the experiments,we have detected the distribution of SAW field in the SAW compressor deposited on the surface of YZ-LiNbO3,and the results are analysed and discussed.
