Simultaneous and separate measurement of in-plane and out-of-plane displacements of a diffused object is presented, which is based on a phase-shifting real-time holographic interferometer. Phase-shifted holographic interferograms are acquired by a TV camera using each symmetrical illumination before and after displacement of the object. Phase calculation methods with these fringe patterns are presented to extract in-plane and out-of-plane displacements separately. Experimental results for two cases of only out-of-plane measurement and separation measurement are given

Polarization measurement system using a rotating analyzer is analyzed for well understanding of polarization phenomena. Principle of the polarization measurement using Jones matrix, rotating analyzer and optical scanning methods is well explained. The method is applied to half and quarter wave plates whose principal axes are rotated. The amplitude ratio angle α, the phase difference δ, the azimuth angle φ and the ellipticity angle χ of an ellipse of polarization afe derived theoretically in cases of the wave plates rotated. The theoretical values of them are plotted in graphs and displayed as trajectories on Poincare\u27 spheres. A simplified experimental setup is shown and experimental results are also given
