TL;DR: In this article, the case of a two-beam phase grating interferometer is discussed on the grounds of polarization analysis as an example, which does not require micro-polarizer arrays or additional software to eliminate noise caused by vibration.

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: In this article, a Mach-Zehnder configuration coupled to a 4-f arrangement using phase gratings placed on the Fourier plane was implemented to analyze phase objects. But the interference of the fields associated with replicated beams, centered on each diffraction order, is achieved varying the spacing of windows with respect to the grating period.

TL;DR: An interferometric method to analyze transparent samples using complex fringes generated by a parallel phase shifting radial shear interferometer using two coupled interferometers that reduces the number of captures needed in phase-shifting interferometry.

TL;DR: In this paper, diffraction properties of several gratings are considered on the basis of the Fourier physical theory, and the interferogram generated for this type of gratings is shown.
