Phase Unwrapping In SAR Interferometry by Tay , Lea Tien

“…Various phase unwrapping algorithms have been developed for extraction of topographic digital terrain model (DTM) and displacement detection in SAR Interferometry since 1988. However, problems such as accuracy and speed of phase unwrapping process still remain a challenge for SAR Interferometry applications. …”

Quadrature wavelength scanning interferometry by Moschetti, Giuseppe, Forbes, Alistair, Leach, Richard K., Jiang, Xiang, O’Connor, Daniel

“…A novel method to double the measurement range of wavelength scanning interferometry (WSI) is described. In WSI the measured optical path difference (OPD) is affected by a sign ambiguity, i.e. from an interference signal it is not possible to distinguish whether the OPD is positive or negative. …”

Constraining symmetron fields with atom interferometry by Burrage, Clare, Kuribayashi-Coleman, Andrew, Stevenson, James, Thrussell, Ben

“…We apply the new constraints from atom-interferometry searches for screening mechanisms to the symmetron model, finding that these experiments exclude a previously unexplored region of the parameter space. …”

Probing dark energy with atom interferometry by Burrage, Clare, Copeland, Edmund J., Hinds, E. A.

“…We derive new limits on the chameleon parameters from existing experiments, and show that most of the remaining chameleon parameter space is readily accessible using atom interferometry.…”

There is more to quantum interferometry than entanglement by Bromley, Thomas R., Silva, Isabela A., Oncebay-Segura, Charlie O., Soares-Pinto, Diogo O., deAzevedo, Eduardo R., Tufarelli, Tommaso, Adesso, Gerardo

“…We demonstrate that entanglement cannot entirely capture the worst-case sensitivity in quantum interferometry when quantum probes are used to estimate the phase imprinted by a Hamiltonian, with fixed energy levels but variable eigenbasis, acting on one arm of an interferometer. …”

Sagnac interferometry with a single atomic clock by Stevenson, Robin, Hush, Michael R., Bishop, Thomas, Lesanovsky, Igor, Fernholz, Thomas

“…So far, the paradigm for matter wave Sagnac interferometry relies on DeBroglie waves and thus on free propagation of atoms either in free fall or within waveguides. …”
