| 摘 要： | 激光诱导荧光技术是一种应用广泛的新型遥测技术，为了指导实际激光诱导荧光探测系统的搭建，介绍了荧光检测原理，设计了激光诱导荧光雷达探测系统。以测量水面石油类污染物为例，通过分析激光诱导荧光雷达探测系统中发射系统及接收系统主要参数对系统信噪比的影响，可根据测量条件选择合适的系统参数。在实验室条件下，选用单脉冲能量为50 μJ的Nd:YAG激光器，接收视场角0.1 mrad，滤光片带宽60 nm的接收系统，可以检验浓度为10个/L的粒子。

| Abstract: | In order to guide setup of fluorescence lidar detecting system practically, model system is designed based on fluorescence detection principle Taking oil pollution measurement on water as an example, this paper analyzes main parameters of launch and receiving system of fluorescence lidar detecting model system and its influence on system signal-to-noise ratio, then proper system parameters are chosen according to testing conditions. Receiving system of laser with 50 μJ single pulse energy, telescope with 0.1 mrad receiving field of view and filter with 60 nm bandwidth are adopted in lab conditions, particles with concentration 10 particles/L can be tested. Results show that this simulation of fluorescence lidar model can satisfy requirements for detecting oil pollution on water surface in laboratory. |
