Abstract
In many open-air monitoring applications of Fourier transform spectrometry (FTS), the lack of a valid background reference spectrum limits the ability to perform quantitative measurements. Suppression of the broad band detector envelope overcomes this limitation. Interferogram processing provides a means of suppressing the broad band background, while maintaining the target spectral signatures of interest. A combination of interferogram segment selection, digital filtering, and pattern discrimination techniques achieve the background suppression of the variable broad band detector envelope. The spectral band position, width, and strength of the target vapor determine the parameters that are used for background suppression. Interferogram segment selection depends primarily on spectral band width. Digital filter design requires inputs of both spectral band position and width. The pattern discrimination techniques compensate for variation in the spectral shape with band strength.
