本文综述了傅里叶变换红外光谱仪在高空测量中应用的发展过程,并着重描述为适应高空测量的需要对迈克尔逊干涉仪的结构进行改进的方法及一些主要实验。美国空军地球物理实验室(AFGL)和犹太州立大学(USU)曾用液氮冷却的调制盘调制大气辐射,入口处用平行光管通到空运器窗外的办法消除直流背景的影响。Rex则采用压电准直和平行四边形悬挂法制成了重量轻、可序列的迈克尔逊干涉仪,动镜的驱动系统使用了线性可变差动转换敏感装置作为反馈控制伺服机构。Mertz用楔型棱镜代替干涉仪的反射镜而获得了宽视场的干涉仪。Stair等人首先使用制冷技术对火箭载运的干涉仪进行全部冷却,制成了液氦冷却红外干涉光谱仪。Huppi等人用焦平面探测器组合的方法提高了
In this paper, the development of Fourier transform infrared spectroscopy (FT-IR) in the application of altitude measurement is reviewed. The method to improve the structure of Michelson interferometer and some major experiments are also described emphatically. The United States Air Force Geophysical Laboratory (AFGL) and the Jewish State University (USU) have used liquid nitrogen cooled modulation disk to modulate atmospheric radiation, the entrance of the collimator to pass through the air window out of the way to eliminate the impact of the DC background. Rex uses a piezoelectric alignment and parallelogram suspension method to produce a lightweight, serializable Michelson interferometer. The drive system of the moving mirror uses a linear variable differential-shift-sensitive device as the feedback control servo. Mertz uses a wedge prism instead of an interferometer mirror to obtain a wide field of view interferometer. Stair et al first used the cooling technique to completely cool the rocket-carrying interferometer and made a liquid helium-cooled infrared interference spectrometer. Huppi et al. Use a combination of focal plane detectors to improve the method
