Available in PDF, EPUB and Kindle. Book excerpt: A real-time system to perform Fourier spectroscopy is described. The spectral distribution is synthesized by the successive summation of cosine functions with amplitudes and frequencies which are determined by the sample points of the interferogram. Summation of these cosine functions is performed in a digital memory oscilloscope which has 1024 addresses. The design criteria and the principles of operation of the system are discussed in detail. Sources of error are examined and several methods of error reduction are discussed. The limitations of this type of system are described and improvements are recommended. Experimental data are presented and the performance of the real-time system is compared to that of a special purpose analog computer, and a digital computer. (Author).

Download or read book Introductory Fourier Transform Spectroscopy written by Robert Bell and published by Elsevier. This book was released on 2012-12-02 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introductory Fourier Transform Spectroscopy discusses the subject of Fourier transform spectroscopy from a level that requires knowledge of only introductory optics and mathematics. The subject is approached through optical principles, not through abstract mathematics. The book approaches the subject matter in two ways. The first is through simple optics and physical intuition, and the second is through Fourier analysis and the concepts of convolution and autocorrelation. This dual treatment bridges the gap between the introductory material in the book and the advanced material in the journals. The book also discusses information theory, Fourier analysis, and mathematical theorems to complete derivations or to give alternate views of an individual subject. The text presents the development of optical theory and equations to the extent required by the advanced student or researcher. The book is intended as a guide for students taking advanced research programs in spectroscopy. Material is included for the physicists, chemists, astronomers, and others who are interested in spectroscopy.
