Abstract

Spectral-domain optical interference phenomena for broadband spectra take in the case of a two-beam interference the forms of the spectral interferograms. The group optical path differences between interfering beams that include information about the distance to be measured and about the properties of propagating wavefronts are inscribed in phase functions of the corresponding spectra interferograms. To recover the phase functions, a standard Fourier-transform method, or a new, recurrence non-linear data processing method can be used.
