Journal ArticleDOI
Sampling Moiré Method for Accurate Small Deformation Distribution Measurement
TL;DR: In this paper, a novel accurate deformation distribution measurement technique by using sampling moire method is proposed, where the measurement area of a target is attached with an adhesive tape of a known pitch grating firstly.
Journal ArticleDOI
Deformation measurement by phase-shifting digital holography
TL;DR: In this article, the out-of-plane displacement of a cantilever is measured by phase-shifting digital holography, and a new method using divided holograms is proposed to decrease the effect of speckle noise.
Journal ArticleDOI
Accurate pixel-to-pixel correspondence adjustment in a digital micromirror device camera by using the phase-shifting moiré method.
TL;DR: An accurate pixel-to-pixel correspondence adjustment in the DMD camera by means of the phase-shifting moiré method is proposed, which provided very accurate adjustment whose error was less than 1/25 pixel.
Journal ArticleDOI
Intensity range extension method for three-dimensional shape measurement in phase-measuring profilometry using a digital micromirror device camera.
TL;DR: The proposed novel intensity range extension method can provide a wider intensity range and higher accuracy for 3D shape measurement than other conventional methods in both underexposed and overexposed areas.
