Abstract
A phase-locked loop (PLL) method application for processing the recorded spectral interferograms obtained under a partial dispersion compensation in a white-light interferometer is considered. The PLL method, which is a special simplified version of the general dynamic recurrence non-linear data processing method, has been realized in iterative m ode which provides the unwrapped phase recovery in temporal Fourier holography. The accuracy of the iterative PLL method has been investigated via the comparison of the unwrapped spectral fringe phase obtained by processing the recorded spectral interferograms with the absolute phase resulting from knowledge of both dispersion in the interferometer and the absolute distance between mirrors of the interferometer.
