Evaluation of spectral modulated interferograms using a Fourier transform and the iterative phase-locked loop method
Spectral modulated interference fringes are observed in the form of the periodical modulation of a broadband spectrum at the output of an interferometer provided with a subsequent spectrometer. The group optical path di...
