Correction of Phase Errors in far Infrared Fourier Spectroscopy

Abstract

Note that from equation (3) and the definition of y(x), the intensity at zero path difference (the white light fringe) is and the spectrum is recovered by multiplying this tranform by e-i¢(w): p(w) ~ e-i¢(w) Ll 5 iwxJ (5) In an ideal two-beam interferometer, the interferogram is the cosine Fourier transform of the frequency spectrum of the I ight detected by the detector. This interferogram is given by
