TL;DR: A simple but effective fringe projection profilometry is proposed to measure 3D shape by using one snapshot color sinusoidal fringe pattern and a simple and robust method is introduced to compensate for nonlinear intensity response of the digital video projector.

TL;DR: In this article, a dual-frequency fringe projection system for 3D surface shape measurement is proposed, which includes two cameras, a DLP 3D projector, and a liquid crystal (LC) shutter glasses.

TL;DR: In this paper, an adaptive filter method based on a deformable window shape was proposed to remove the noise of wrapped phase fringe patterns in electronic speckle pattern interferometry (ESPI), which automatically adjusts its size, shape, and direction according to the direction and curvature of the phase fringe pattern.

TL;DR: Three-dimensional shapes of objects were evaluated with modified phase-shift lateral shearing interferometry illumination and radial basis function to improve the quality of fringe patterns and the reconstructed height distributions were in good accordance with the referenced data.

TL;DR: A panoramic dual-directional shearography system is proposed to simultaneously determine out-of-plane deformation derivatives in two directions and globally inspect the object to be tested and theoretical analysis and experimental results demonstrated the utility of the system.
