The contribution of the third-generation Fourier spectrometer, built at the Laboratoire Aimé Cotton and currently at the Laboratoire d'Infrarouge, to meteorological and high resolution Doppler-limited measurements is reported citing typical examples and the latest instrumental improvements. A tilt-compensated triple-pass system for use with previously built Fourier spectrometers to increase the resolution by 3 is described. The resulting width of the apparatus function of the triple-pass third-generation interferometer is better than 10(-3)cm(-1) and can be meaningfully expressed in frequency units. Its actual value is 27 MHz. For the first time a spectrometer is able to give very wide spectral range information with a resolving power sufficient to analyze sub-Doppler spectra.
本文报道了由艾梅·科顿实验室制造、现位于红外实验室的第三代傅里叶光谱仪在气象学和高分辨率多普勒极限测量方面的贡献，并列举了典型示例和最新的仪器改进情况。文中描述了一种用于先前制造的傅里叶光谱仪的倾斜补偿三程系统，该系统可将分辨率提高3倍。三程第三代干涉仪的仪器函数所得宽度优于10^(-3)厘米^(-1)，并且可以用频率单位有意义地表示。其实际值为27兆赫兹。首次有一台光谱仪能够提供非常宽的光谱范围信息，同时具有足以分析亚多普勒光谱的分辨能力。
