摘要：

Many single shot, single pixel underwater LIDAR systems employ high performance photo-multiplier tubes (PMTs) in their receivers. While PMTs offer high gain with a low noise factor, the dynamic range of the output signal is limited by signal induced artifacts. These artifacts include decaying signals with long time constants and short duration "ghost reflection" signals. This paper will characterize the signal-induced artifacts for various single pixel PMTs with different photo-cathode materials and dynode materials.
