A completely general analysis of interferograms reveals the phases as well as the amplitudes of the Fourier components. Even though the phase information is usually neglected, it can serve several useful purposes. 1° It directly facilitates phase corrections for off-center interferograms. The correction also eliminates the systematically positive contribution of noise. Furthermore the correction is accomplished without the necessity of any symmetry around the white light fringe or the registration of a sample point on that fringe. The accurate location of the white light fringe is incidently established without recourse to interpolation. 2° It provides for easy evaluation of the significance of weak signals and also indicates the direction ...
