【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50μJ的Nd:YAG激光器,接收视场角0.1 mrad,滤光片带宽60nm的接收系统,可以检验浓度为10个/L的粒子。
[Abstract]:Laser induced fluorescence (LIF) is a new type of telemetry technology, which is widely used. In order to guide the construction of laser induced fluorescence detection system, the principle of fluorescence detection is introduced. The laser induced fluorescence radar detection system is designed. The influence of the main parameters of the transmitting system and the receiving system on the signal-to-noise ratio of the system is analyzed by taking the measurement of petroleum pollutants on the surface as an example. The suitable system parameters can be selected according to the measurement conditions. In the laboratory condition, the Nd:YAG laser with 50 渭 J single pulse energy is used to receive the field of view angle of 0.1 mrad. A receiver with a bandwidth of 60 nm can be used to detect particles with a concentration of 10 / L.
