摘要
多普勒激光雷达在大气风场探测中已经得到广泛应用.相比于Fabry-Perot(F-P)干涉仪、Fizeau干涉仪,Mach-Zehnder(M-Z)干涉仪作为鉴频器具有透过率高、探测谱的范围宽、能进行视场展宽而获得大光通量、所成直条纹可以与CCD匹配等优点,同时也可以实现大的风速探测范围,弥补现有直接探测多普勒测风激光雷达探测范围较小,探测灵敏度的非线性问题.分析了基于M-Z干涉仪条纹成像技术的激光雷达大气风场探测原理,对干涉仪鉴频系统进行了参数优化设计及仿真分析,通过设定实验参数,获得仿真结果,进行数据反演,得到风速值与理论结果基本一致.
Doppler lidar was widely used for wind measurement.Compared with Fabry-Perot(F-P) interferometer and Fizeau interferometer,Mach-Zehnder(M-Z) interferometer have the advantages of high transmittance,wide spectral range,wide field of view and producing linear fringe.It can realize wide wind range detection and make up smaller detection range and nonlinear detection sensitivity of present technology.Wind measurement theory based on fringe imaging M-Z interferometer is analyzed.The parameters of interferometer system are optimized and then the system is designed by using a numerical simulation.The results show that the wind velocity retrieved agrees with theoretical wind velocity.
