| 摘 要： | 文中讨论了激光对潜通信光信道各种介质对冲激光能量传递的影响，给出了能量方程和信道介质对脉冲激光能量传递的衰减值范围。研究了光电倍增管的增益变化特性，据此设计出了一种实用的激光探测信号动态范围自适应调节系统，该系统自动调节范围可达10^4，能满足激光对潜通信系统在不同天气、不同海况及不同海域等条件下的应用。

| Abstract: | The laser signal energy transmission calculation eq uation and the total rang of the energy attenuation caused by the channel medium s are given.The gain varies feature of PMT is described. The adaptive adjusting system of the detected signal is designed. The auto-adjusting range of 10 4 is obtained. This is satisfied for the submarine laser communication test system. |
