Journal ArticleDOI
Automated phase-measuring profilometry of 3-D diffuse objects
TL;DR: The high resolution surface profile of a 3-D diffuse object is obtained by measurement of the phase distribution across the image of a projected sinusoidal grating deformed by the surface, based on phase-shifting interferometric techniques.
Journal ArticleDOI
Automated phase-measuring profilometry: a phase mapping approach.
TL;DR: It is shown that the object height can be computed by measuring this phase accurately using phase modulation methods and by determining points on the reference plane and the object having identical phases.
Journal ArticleDOI
Optical three-dimensional sensing by phase measuring profilometry
Maurice Halioua,Hsin-Chu Liu +1 more
TL;DR: In this paper, a sinusoidal grating structure is projected onto a diffuse three-dimensional surface, and the resulting deformed grating image is detected by a solid state array camera and processed by a microcomputer using interferometric phase measuring algorithms.

Method and apparatus for surface profilometry
TL;DR: In this article, phase differences between images of an object and a reference plane are used to obtain a measure of the object height, and phase measurements of deformed grating images are used in performing improved optical profilometry.
Journal ArticleDOI
Projection moire with moving gratings for automated 3-D topography
TL;DR: A method is presented that permits a vast increase in the capability of projection moire topography by simultaneous translation of the reference and object gratings to generate high-definition contour fringes without any of the artifacts associated with ordinary moire.
