Vortex beams with helical phase, carrying phase singularity and orbital angular momentum,
have attract great attention in the past decades due to their wide applications in optical …

The challenge of phase recovery from the experimentally available magnitude of the signal
appears in various fields of science and engineering. To prepare a broad framework and …

We propose and experimentally demonstrate a noninterferometric method to quantitatively
determine the topological charge and complete phase structure of a vortex beam scrambled …

The distribution of degree of coherence of a partially coherent vortex beam reveals rich
information about the vortex phase, and it is known that one can determine the topological …

Ever since vortex beams were proposed, they are known for owning phase singularity and
carrying orbital angular momentum (OAM). In the past decades, coherent optics developed …

In the theory of partial coherence, coherence singularities can occur in the spectral degree
of coherence (SDOC): in case the fields at two different points are completely uncorrelated …

It is well known that when a laser is reflected from a rough surface or transmitted through a
diffusive medium, a speckle pattern will be formed at a given observation plane. An …

Optical vortex beams are under considerable scrutiny due to their demonstrated potential for
applications ranging from quantum optics to optical communications and from material …

Encoding information using the topological charge of vortex beams has been proposed for
optical communications. The conservation of the topological charge on propagation and the …

A technique based on the superposition of two uncorrelated speckle patterns and speckle
contrast measurement is proposed and demonstrated to track the polarization rotation of an …
