本文报导了一种新型的付里叶光谱仪。分析了多色平行光入射到麦克尔逊干涉仪中,在零光程附近的等厚干涉强度分布。证明了它恰好是入射光光谱的付氏谱。因而可以用由记录等厚干涉强度分布替代以前的用移动反射镜得到付氏谱的方法,简化了仪器。为了获取入射光谱的真实光谱讯息,必须对所获的付氏谱进行逆付氏变换。本文提出用光学 This article reports a new type of Fourier spectrometer. The isometric interference intensity distribution of multi-color parallel light incident on the Michelson interferometer is analyzed. It is proved that it happens to be the SUF spectrum of the incident light spectrum. Thus, it is possible to simplify the instrument by replacing the previous Fourier series with moving mirrors by recording the isopronic interference intensity distribution. In order to obtain the true spectral information of the incident spectrum, it is necessary to perform the inverse Fourier transform on the obtained Fourier spectrum. This paper presents the use of optics
