Abstract
A phase-locked loop method is applied in processing the spectral interferograms resolved in a narrow spectral range in a dispersive Michelson interferometer including optical elements. The unwrapped spectral fringe phases with 2π ambiguity are determined and a simple procedure in removing the ambiguity is applied to obtain the effective thicknesses of the optical elements knowing their dispersion. The effective thicknesses determined in two cases are compared with those obtained by measuring the equalization wavelengths. A Fourier transform method is applied in processing the spectral interferogram resolved over a wide spectral range in a slightly dispersive Michelson interferometer including a cube beamsplitter. The ambiguous spectral fringe phase is determined and a procedure in removing its ambiguity is applied to obtain the effective thickness of the beamsplitter.
