In fringe projection profilometry (FPP), temporal phase unwrap** is an essential
procedure to recover an unambiguous absolute phase even in the presence of large …

Phase retrieval from fringe images is essential to many optical metrology applications. In the
field of fringe projection profilometry, the phase is often obtained with systematic errors if the …

Full-field fringe projection techniques have been widely studied in academia and applied in
industrial fields because of the advantages of non-contact operation, fast full-field …

Fringe projection profilometry has been widely used for 3-D measurement, but the gamma
nonlinearity severely affects the accuracy. Ideally, the histogram of the undistorted phase is …

For fringe projection profilometry (FPP), phase extraction accuracy determines three-
dimensional (3D) measurement precision. The combination of phase-shifting (PS) and multi …

Fascinated by the marvelous work that Professor Jim Wyant has done in both academy and
industry, I decided to pursue a career in the field of 3D optical metrology in my early …

Three-dimensional profilometry by sinusoidal fringe projection using phase-shifting
algorithms is usually distorted by the nonlinear intensity response of commercial video …

This paper makes use of Hilbert transform to analyze and compensate the phase error
caused by the nonlinear effect in phase shifting profilometry (PSP). The characteristics of the …

In fast phase measurement profilometry (PMP) systems, it is very important to use minimum
image number to achieve full spatial resolution 3D measurement of arbitrary shape objects …
