摘　　要：利用Fabry-Perot干涉仪(FPI)测量气辉的多普勒频移和展宽是目前对中高层大气风场和温度场进行测量的主要方法之一。通过对FPI成像过程的物理描述,引入了一个表征系统偏差的特征量,给出了系统光学传输函数的傅立叶级数解。重要的是,在傅立叶系数与特征量之间建立起了明确的数学关系,并与632.8nm氦氖激光多光束干涉实验拟合出的傅立叶系数相符。Measurements of atmospheric emissions,such as aurora and airglow,using Fabry-Perot interferometer(FPI) have enabled the remote sensing of atmospheric wind and temperature.Introduce an eigenvalue that signify the system error based on the physical description of FPI system and give a Fourier series expression of the system transfer function.An explicit relationship between the Fourier coefficient and the exigent value is founded,the relationship is well proved by experiments using 632.8nm He-Ne laser as a simulation of the systemic transfer property.
