Paper Abstract

Various aspects of interferogram analysis are reviewed. Fixed interferogram evaluation, fringe measurements, the global interpolation of interferograms, the application of Zernike polynomials, Fourier analysis of interferograms, and phase-shifting interferometry are described. Under the latter heading, the methods of zero crossing, phase lock, phase stepping, integrating phase shifting, and sub-Niquist and two-wavelength interferometry are considered.
