Dynamic 3D shape measurement based on the phase-shifting moiré algorithm
Canlin Zhou, Shuchun Si, XiaoLei Li +3
In order to increase the efficiency of phase retrieval,Wang proposed a high-speed moire phase retrieval method.But it is used only to measure the tiny object. In view of the limita…
Enhanced Dual-frequency Pattern Scheme Based on Spatial-temporal Fringes Method
Minmin Wang, Canlin Zhou, Shuchun Si +4
One of the major challenges of employing a dual-frequency phase-shifting algorithm for phase retrieval is its sensitivity to noise. Yun et. al [H Yun, B Li, S Zhang. 2017] proposed…
Extended Depth-range Dual-wavelength Interferometry Based on Iterative Two-step Temporal Phase-unwrapping
Minmin Wang, Canlin Zhou, Shuchun Si +3
Phase retrieval is one of the most challenging processes in many interferometry techniques. To promote the phase retrieval, Xu et. al [X. Xu, Y. Wang, Y. Xu, W. Jin. 2016] proposed…
Robust Wrapping-free Phase Retrieval Method Based on Weighted Least-square Method
Minmin Wang, Canlin Zhou, Shuchun Si +3
For many profilometry techniques, phase unwrapping is one of the most challenging process. In order to sidestep the phase unwrapping process, Perciante et. al [Appl Opt 2015; 54(10…
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…
