One-shot phase-shifting phase-grating interferometry with modulation of polarization: case of four interferograms.
Gustavo Rodriguez-Zurita,Cruz Meneses-Fabian,Noel-Ivan Toto-Arellano,J F Vázquez-Castillo,Carlos Robledo-Sanchez +4 more
TL;DR: An experimental setup for optical phase extraction from 2-D interferogram extraction using a one-shot phase-shifting technique able to achieve four interferograms with 90 degrees phase shifts in between is presented.
Journal ArticleDOI
Edge effects with the Preston equation for a circular tool and workpiece
Alberto Cordero-Dávila,Jorge González-García,María Pedrayes-López,Luis Alberto Aguilar-Chiu,Jorge Cuautle-Cortés,Carlos Robledo-Sanchez +5 more
TL;DR: A new model in which the pressure is higher at the edge is applied to the case of a circular tool that polishes a circular workpiece and correctly predicts that a greater amount of material is removed from the edge of the workpiece.
Journal ArticleDOI
Generalized phase-shifting interferometry by parameter estimation with the least squares method
Rigoberto Juarez-Salazar,Carlos Robledo-Sanchez,Cruz Meneses-Fabian,Fermin Guerrero-Sanchez,L. M. Arévalo Aguilar +4 more
TL;DR: This algorithm, by a new interferogram normalization procedure, can handle interferograms with variable spatiotemporal visibility overcoming the restriction and drawbacks from usual variable spatial visibility approaches.
Journal ArticleDOI
Theory and algorithms of an efficient fringe analysis technology for automatic measurement applications
TL;DR: A full scheme for phase evaluation, applicable to automatic applications, is proposed, which consists of a fringe-pattern normalization method, Fourier fringe-normalized analysis, generalized phase-shifting processing for inhomogeneous nonlinear phase shifts and spatiotemporal visibility, and a phase-unwrapping method by a rounding-least-squares approach.
Journal ArticleDOI
Common-path phase-shifting interferometer with binary grating
Cruz Meneses-Fabian,Gustavo Rodriguez-Zurita,J F Vázquez-Castillo,Carlos Robledo-Sanchez,Victor Arrizón +4 more
TL;DR: In this paper, an experimental setup for phase extraction of 2D phase distributions using a common-path interferometer consisting of two windows in the input plane and a translating grating as spatial filter is presented.
