Singularity-Spreading Phase Unwrapping

IEEE Transactions on Geoscience and Remote Sensing, 2007
How to process phase singular points (SPs), or residues, is a difficult problem in a 2-D phase-unwrapping process to generate digital elevation maps (DEMs). Although the minimum-cost network-flow method is an effective and widely used technique, some problems still remain.

Single-slit diffraction of an optical beam with phase singularity

Optics and Lasers in Engineering, 2009
Single-slit diffraction of an optical beam carrying phase singularity is presented. Due to azimuthal phase dependence, the diffraction pattern of the singular beam differs from that of a plane wave. The fringes in the diffraction pattern of singular beam

Shearograms of an optical phase singularity

Optics Communications, 2008
Shearograms are known to represent phase gradients but when vortices are present in the optical field, these do not represent true phase gradients. Phase gradients of an optical phase singularity are presented. A lateral shear interferometer is used for obtaining shearograms of optical fields with vortices.
