WebPhase unwrapping, either spatial or temporal, plays an important role in fringe projection profilometry (FPP) to recover a continuous phase map. Compared with the spatial phase unwrapping (SPU), the temporal phase unwrapping (TPU), including multi/two-frequency, phase coding, and gray code methods, is more widely used due to its ability to measure … WebJul 23, 2010 · In this paper, we propose a least-squares-based method for multitemporal synthetic aperture radar interferometry that allows one to estimate deformations without the need of phase unwrapping. The method utilizes a series of multimaster wrapped differential interferograms with short baselines and focuses on arcs at which there are no …

WebApr 27, 2024 · In conclusion, we showed here the synthesis, isolation and structural characterization of the geometrically constrained SP phosphoranide 1−. A preliminary reactivity study showed that 1− reacts with MeI, most probably as a nucleophile leading to 1-Me. In contrast, the reaction of 1− with benzophenone involves a SET mechanism to … WebDec 5, 2024 · Shape measurement based on temporal phase unwrapping of a NIST traceable gauge.
