Influence of core misalignment and distortion on the Fresnel and holographic images of superconducting fluxons

Abstract
The model developed to interpret holographic and out-of-focus images of superconducting vortices or fluxons in thin specimens has been implemented to treat effects such as misorientation or even distortion of the flux line. It is shown that in this way the anomalous shape of some globules in out-of-focus images of the flux line lattice as well as the local trend of the interference fringes in holographic reconstructed images can be satisfactorily interpreted.
