Precise and Fast Phase Wraps Reduction in Fringe Projection Profilometry
Minmin Wang, Guangliang Du, Canlin Zhou +4
The number of phase wraps in 2D wrapped phase map can be completely eliminated, or greatly reduced by frequency shifting. But the wraps usually cannot be optimally reduced using th…
Improved phase-unwrapping method using geometric constraints
Guangliang Du, Minmin Wang, Canlin Zhou +4
Conventional dual-frequency fringe projection algorithm often suffers from phase unwrapping failure when the frequency ratio between the high frequency and the low one is too large…
Comment on "Dual-wavelength in-line phase-shifting interferometry based on two dc-term-suppressed intensities with a special phase shift for quantitative phase extraction"
Minmin Wang, Guangliang Du, Canlin Zhou +5
We comment on the recent Letter by Xu and Wang et al. [Opt. Lett. 41, 2430 (2016)] in which an approach of quantitative phase extraction in dual-wavelength in-line phase-shifting i…
Enhanced high dynamic range 3D shape measurement based on generalized phase-shifting algorithm
Minmin Wang, Guangliang Du, Canlin Zhou +5
It is a challenge for Phase Measurement Profilometry (PMP) to measure objects with a large range of reflectivity variation across the surface. Saturated or dark pixels in the defor…
One shot profilometry using iterative two-step temporal phase-unwrapping
Guangliang Du, Minmin Wang, Canlin Zhou +4
This paper reviews two techniques that have been recently published for 3D profilometry and proposes one shot profilometry using iterative two-step temporal phase-unwrapping by com…
Improved method for phase wraps reduction in profilometry
Guangliang Du, Minmin Wang, Canlin Zhou +4
In order to completely eliminate, or greatly reduce the number of phase wraps in 2D wrapped phase map, Gdeisat et al. proposed an algorithm, which uses shifting the spectrum toward…
An algorithm to increase the residues of wrapped-phase in spatial domain
Guangliang Du, Minmin Wang, Canlin Zhou +4
In phase unwrapping, the locations and densities of residues are indicative of the severity of the unwrapping problem. The residues are used to detect and evade inconsistent phase…
