Fourier Transform Spectrometry is of immediate use to those who use Fourier transform spectrometers in their research, or are considering their use. The authors' presentations enable readers to obtain a clear understanding of FTS, which is crucial to their studies and research. Due to the increasing complexity and commercialization of instrumentation, achieving optimum performance in research applications and automated usage can be challenging. For example, a thorough understanding of the instrument can dramatically affect the outcome of the experiment and the generation of reliable data in applications where conditions are not ideal and resulting signals are weak. This book provides a comprehensive discussion of FTS from the ground up, covering basic concepts, instrumentation, data-processing algorithms, and techniques for computerized spectral analysis. "Fourier Transform Spectrometry provides essential background in Fourier analysis, systematically develops the fundamental concepts governing the design and operation of Fourier transform spectrometers, and illustrates every concept pictorially. Methods for transforming the interferogram and phase correcting the resulting spectrum are presented, with a focus on understanding the capabilities and limitations of the algorithms. Techniques of computerized spectrum analysis are discussed in a way that enables spectroscopists to understand the numerical processing algorithms without becoming computer programmers. Methods for determining the accuracy of numerical algorithms are detailed and compared pictorially and quantitatively. Algorithms for line finding, fitting spectra to voigtian profiles, filtering, Fourier transforming, and spectrum synthesis are a basis for spectrum analysis tools from which complex signal-processing procedures can be constructed.". "This book is of immediate value to those who use Fourier transform spectrometers in their research or are considering their use. It gives the mathematical and physical background for understanding the operation of an ideal interferometer, illustrates those ideas with example interferograms obtained via ideal and nonideal interferometers, and shows how the maximum amount of information can be extracted from the interferograms. Finally, it shows how sampling and noise affect the spectrum."--BOOK JACKET.
