Optical Profilometry of Nail Dystrophies

Dermatology, 1995
Optical profilometry after nail shadowing is introduced as a new technique to quantify nail surface alterations. Objective evaluations can be performed in vivo as well as on nail clippings and silicone rubber replicas. Trachyonychia, pittings, grooves and any other type of onychodystrophy are conveniently defined by 3 profilometric parameters: the mean

Adaptive Profilometry for Industrial Applications

1993
In 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.

Comparing Hilbert transform profilometry and Fourier transform profilometry (Conference Presentation)

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
