傅里叶变换光谱学（FTS）传统上被认为是一种红外光谱技术，它向可见光和紫外光区域的扩展增加了它在分析原子光谱学、天体物理学和大气物理学中的应用范围。FTS和光栅光谱的相对优势必须在这些较短的波长进行不同的评估，它表明，非常准确的波数尺度和高分辨率通常是FTS提供的最重要的优势。比较了吸收光谱和发射光谱以及扫描光谱和多通道光栅光谱仪在相同光源和相同分辨率的两种光谱仪上可以获得的信噪比。FTS升级数据库的适用性，无论是原子发射光谱和天体物理学和大气物理学的应用，进行了讨论，并说明了在所有这些领域取得的进展的例子。
The extension to the visible and ultraviolet regions of Fourier transform spectroscopy (FTS), traditionally regarded as a technique for the infrared, has increased the range of its applications to analytical atomic spectroscopy, astrophysics and atmospheric physics. The relative advantages of FTS and grating spectroscopy have to be assessed differently at these shorter wavelengths; it is shown that the very accurate wavenumber scale and the high resolution attainable are usually the most important advantages offered by FTS. The signal-to-noise ratios that can be obtained with the two types of spectrometer with the same source and the same resolution are compared for absorption and emission spectra, and for scanning and multi-channel grating spectrometers. The suitability of FTS for upgrading databases, both for atomic emission spectroscopy and for astrophysical and atmospheric physics applications, is discussed and illustrated with examples of advances made in all these fields.
