摘要
出射激光脉冲能量变化对激光雷达的测量数据有很大影响,需对其进行实时、准确测量。 针对激光雷达出射激光脉宽窄、不易实现高频电路采集的问题,设计了一个基于峰值采样保持电路的 脉冲能量监测系统。对脉宽为10 ns、重复频率分别为20、60、100 Hz的模拟脉冲进行了实时监测,结果 表明该系统能很好地检测激光出射能量,没有脉冲遗漏现象。在激光雷达观测实验中,该监测系统输出的 电压值与实测激光脉冲能量有较好的线性关系,为激光雷达数据反演提供了修正依据。
Abstract
Variation of output laser pulse energy has great influence on the measured data of radar, so the output laser pulse energy must be measured accurately in real-time. Aiming at the problem that output laser pulse width is very narrow, and it is difficult to achieve high frequency acquisition circuit, a pulse energy monitoring system is designed based on the peak sampling and holding circuit. In situ monitoring of simulated pulses with pulse width of about 10 ns and repetition rates of 20, 60, 100 Hz is carried out. Results show that the system can accurately detect laser emitting energy without any pulse missing. There is a good linear relationship between the system output voltage and measured laser pulse energy in lidar observation experiments, which provides a correction basis for lidar data inversion.
