TL;DR: An interferometric method to measure the slope of phase objects is presented by implementing a polarizing phase-shifting cyclic shear interferometer coupled to a 4-f Fourier imaging system with crossed high-frequency Ronchi gratings.

TL;DR: A parallel two-step polarizing phase shifting interferometer based on a Double Cyclic Shear Interferometer (DCSI) is proposed in this paper for quantitative phase imaging and presents better stability against external configurations than other types of interferometers.

TL;DR: It is shown that the zero-order elimination by the phase-shifted holograms is better than working with weak-order beam and average intensity removal methods.

TL;DR: In this article, an optical system capable of simultaneously grabbing three phase-shifted interferometric images was developed for dynamic temperature field measurements of a thin flame, which is based on measuring the refraction index difference by solving the inverse Abel transform, which requires information obtained by the fringe order localization.

TL;DR: In this paper, a phase grating is used to replicate the interference patterns and phase shifts modulated by polarization, and an interferometric method to measure the radial slope of dynamic transparent samples is presented.
