Paper Abstract

Spectral modulated interferograms (channeled spectra) characterize dispersion of optical samples and allow measuring distances and displacements. Useful information is contained in spectral fringe frequency and phase that can be evaluated dynamically by the extended Kalman filtering method based on recurrence prediction-correction processing procedure. The method provides direct dynamic estimates of unwrapped fringe phase within single fringe sample series. The accuracy of the extended Kalman filtering method has been investigated experimentally by processing recorded spectral interferograms.
