    • Abstract
  • In order to reduce distortion of remote signal induced by wide dynamic range of lidar signal,a voltage controlled transmission modulation was used to suppress the dynamic range of lidar signal.The result of simulation indicates that the minimum transmissivity of the system is 4.05×10-5 and the dynamic range can be reduced to 4 orders of magnitude.The system receives both ordinary light and extraordinary light, so it can avoid the disadvantage of the time-dependent attenuator in whieh only polarizing light in one direction can be received.It provides new valuable approach to suppress lidar dynamic range.
