In this paper, a simple isoclinic phase map unwrapping method is proposed to retrieve map with ambiguities at photoelastic isotropic points. Regional phase unwrapping method is also utilized to enhance the retrieving efficiency after all phase inconsistencies have been fully detected and branch cutting works have been properly done to ensure blockings of all the paths which could cause incorrect integrations while involuntarily crossing them. The correctly retrieved isoclinic data are then fed into isochromatic formulation, and as a consequence an inconsistency free isochromatic phase map will be obtained. This map can be unwrapped by any simple and fast unwrapping algorithm accurately and effectively. Circular disk and ring under diametric compression samples are both applied for the verification of the proposed algorithm. The experimental results show the proposed algorithm can successfully solve the annoying problems occurred at photoelastic isotropic points with a processing time of roughly 2 seconds for a 420 x 420 pixels map by a general personal computer.
We realize a topological superconductor (TSC) in correlated
Topological insulator - the interacting spinful Haldane model. We consider the
Electrons on the Haldane model with on-site negative-U interaction and then
Study its properties by mean field theory and random-phase-approximation (RPA)
We construct new equations of state for baryons at sub-nuclear densities for
The use in core-collapse simulations of massive stars. The abundance of various
Nuclei is obtained together with thermodynamic quantities. A model free energy
Is constructed, based on the relativistic mean field theory for...
We consider networks where nodes differ in clock frequency and phase, and aim
To synchronize to a master clock. Nodes exchange packets and are able to
Exchange and measure noisy time information. When the measurement noise is
Gaussian, we propose two fully distributed, cooperative network synchroniz...
