| 摘 要： | 在AML-2车载测污激光雷达中,对装有不同气体的拉曼管进行拉曼激发获得相应的强、弱吸收关波长。针对差分雷达激光发射光路转换的特点及提高雷达监测的实时性能要求,基于激光偏振调制原理提出了激光雷达光路分束设计的新方法,对该方法可行性进行了理论分析,并对改进光路的能量损失进行了估算,模拟结果显示改进后的系统延长了仪器的使用寿命,提高了测量的实时性。为提高差分激光雷达实时监测性能提供了一种新方法。 |

| Abstract: | The on and off wavelengths are obtained by stimulating the Raman tube filled with different gases in AML-2 air-monitoring lidar.According to the characteristic of lidar light transfer path,a new design about light which introduces the idea of beam-splitting based on polarization modulation is presented to improve the real-time performance.Feasibility of the new method is demonstrated and energy loss is evaluated.The simulated results show that the improved system increases the service life of intruments and the real-time performance of lidar.It provide a choice to improve real-time performance of differential absorption air pollution monitoring lidar in practice. |
| Keywords: | lidar differential absorption beam splitting real time pollution monitoring |
