This book is a bible in Fourier Transform spectroscopy. The authors are pioneers in the FT application and the book explains the theory very clearly and easy to understand.
This book applies the theory of Fourier transforms to their use in spectroscopy, based on using graphical examples to illustrate the mathematical properties discussed. It is useful for areas of spectroscopy other than those in the titles, since the concepts are applicable to many FT methods of data acquisition.
