Abstract

The effects of signal-averaging in Fourier transform infrared spectrometry (FT-IR) have been well characterized and are well known. In some applications, such as aas chromatography/Fourier transform infrared spectrometry (GC/FT-IR), it may be necessary to collect single-scan interferograms. There is considerable interest in the direct processing of interferometric data as opposed to spectral domain data processing. Areas of study to which interferometric data handling have been directed are chromatogram reconstruction, search systems and compound classification. Any instability in the interferometer leads to noise in the interferogram. The character of this noise and its effects have been investigated.
