Volume moiré tomography based on double cross gratings for real three-dimensional flow field diagnosis
TL;DR: The scalar diffraction theory is used for analyzing the imaging process of VMT based on double cross gratings to achieve the explicit form of shearing phase and the real temperature distribution of a propane flame is reconstructed, which can confirm the VMT method.

Theoretical analysis and experimental verification of six-step spatial phase-shifting shearing interferometry by double gratings
TL;DR: A new spatial phase-shifting shearing interferometry that consists only of a crossed grating and a linear grating is presented that can be acquired simultaneously and indicates that phase shifts are symmetrically and consistently distributed in the vertical and horizontal directions.

Two-step spatial phase-shifting radial shearing interferometery with circular gratings
TL;DR: A simple radial shearing interferometery with circular gratings to measure the radial first-order derivative of arbitrary wavefront phase and a two-step phase-shifting algorithm with arbitrary phase-shift value is proposed for phase retrieval.

Implementation of multidirectional moiré computerized tomography: multidirectional affine calibration.
TL;DR: A six-directional moiré tomographic system is designed and a multidirectional affine calibration method is proposed to determine the extrinsic and intrinsic parameters of tomographic projections and the 3D distributions of flow field can be reconstructed.
