Adaptive Profilometry for Industrial Applications
1993In this chapter a review of optical profilometry techniques is presented. Particular emphasis is given to industrial applications of these methods, especially their system adaptiveness. The main features of an optical adaptive profilometer, which makes use of a Liquid Crystal projector, are presented.

Dimensional Optical Metrology and Inspection for Practical Applications VIII, 2019
Three-dimensional (3D) shape measurement methods based on fringe analysis could achieve high resolution and high accuracy. Fourier transform profilometry (FTP) uses a single fringe pattern is sufficient to recover the carrier phase for 3D shape measurement. Basically, FTP method applies Fourier transform to a fringe image and extracts the desired phase

Profilometry by fringe projection
Optical Engineering, 2003We present a method to obtain profilometry of a suitable ob- ject by fringe projection. The method is appropriate to the case of large objects as compared to the distance from the illuminating source, that is, a nonconstant equivalent wavelength. We develop an experiment to lat- erally displace a set of fringes on a sphere and obtain quantitative re ...

Profilometry In The Angstrom Region
SPIE Proceedings, 1989An interferometric system, based on heterodyne principle is described and which enables profile measurements of a surface with a high accuracy. It is possible to measure height variations of 4 Angstroms with a spatial resolution of 1 micrometer. Fran the surface height measurements, there were calculated its statistical properties, such as the R of the
