摘要
基于激光监听技术的原理,利用MatLab仿真软件进行激光监听技术研究,分析了光束入射角与光斑移动距离关系以及激光光斑在探测器上的位置对于探测灵敏度的影响,得到在探测器距光斑中心为光束半径一半时,光强变化量最大,监听声音最清晰。通过实验也验证了相关分析。
In accordance with the theory of laser monitoring technology, the relationship between incidence angle of laser beam andlight spot moving distance as well as the effect of laser spot’s location on the detector on detection sensitivity were analyzed using MatLabsimulation software to research LMT. It was found that variation of light intensity was maximum and monitoring voice was clearest when thedistance between detector and light spot was equal to half of beam radius. The relevant analysis results were also verified by experiment.
