摘要:

机载海洋荧光激光雷达是最有效的海洋环境监测手段之一, 世界上许多国家发展了机载海洋荧光激光雷达系统,并成功的应用于业务化测量。根据国际机载荧光激光雷达系统发展趋势,本文对基于512通道ICCD的机载海洋荧光激光雷达系统进行了实验室实验模拟和计算,对其可行性进行了评估。本文采用单脉冲能量70uJ的355nm Nd:YAG激光器作为激发光源,直径100mm,的透镜收集探测距离5米远荧光信号,信号具有较好信噪比。模拟计算表明,对于同样基于ICCD探测的机载海洋激光雷达,采用20Hz、单脉冲能量80mJ的激光器和200mm口径望远镜在150米探测距离可获得与实验室相当的结果。

Abstract:

As one of the most effective method of ocean environment monitoring, airborne ocean fluorescence lidar has been developed in many countries, and has been widely used in operation. Following the trend in the world, in this paper, a 512 channels ICCD was used as ocean lidar’s detector. With a 70uJ single pulse energy, 355nm laser and the 512 channels ICCD, we simulated the performance of airborne ocean lidar in laboratory. The water sample was put in 5 meters and the fluorescence signal was collected with a 100mm diameter lens. The experimental results shows a good signal noise ratio. Based on the simulation experimental results, we can include that a real airborne ocean lidar with a 20Hz, 80mJ single pulse energy, and 200mm diameter collection telescope has nearly the same performance with the lab lidar system.
