Measuring optical vortices in a speckle pattern using a multi-pinhole interferometer.
We show that it is possible to find and characterise optical vortices in a speckle pattern using a multi-pinhole interferometer. This measurement does not require an interferometric setup, providing
Comparison of optical vortex detection methods for use with a Shack-Hartmann wavefront sensor.
Two methods of detecting optical vortices from Shack-Hartmann wavefront sensor (SHWFS) data, the vortex potential and the contour sum methods are compared.

The influence of the morphology and the separation distance from oppositely charged vortices on the Shack-Hartmann vortex detection is studied and numerical simulations for vortex detection under these turbulent atmospheric circumstances are provided.
Detection of phase singularities with a Shack-Hartmann wavefront sensor.
This work investigates the detection of phase singularities with the aid of a Shack-Hartmann wavefront sensor and shows that, in spite of some systematic deficiencies inherent to the Shack- Hartmann wave front sensor, it can be used for the reliable detection ofphase singularities, irrespective of their morphologies.
Examination of singular scalar light fields using wavelet processing of fork fringes.
Corroboration of simulation and experimental studies of integer and noninteger singular light beams as well as speckle fields reported in the literature and analyzed using different approaches is presented.
Using a multipoint interferometer to measure the orbital angular momentum of light in astrophysics
Recently it was shown that the orbital angular momentum of light can be measured using a multipoint interferometer, a system in which the light from several point measurements is interferometrically
Common-path lateral-shearing nulling interferometry with a Savart plate for exoplanet detection.
A Savart plate is placed between crossed polarizers to produce a lateral shear and realize fully achromatic and highly stable nulling interference for starlight and construct a double-shearing interferometer using two Savart plates for implementing orthogonal x and y shears.
Scattering through fluids: speckle size measurement and Monte Carlo simulations close to and into the multiple scattering.
Measurements in transmission of the speckle produced by scattering liquid media: diluted milk and water solutio ns of polystyrene-microspheres of different diameters are reported and a method to differentiate media is proposed.

The phase singularity density is coincident with the theoretical results under a weak fluctuation condition, and has a slowly increasing manner with the Rytov index in the strong fluctuated condition.
Method for probing the orbital angular momentum of optical vortices in electromagnetic waves from astronomical objects.
This method, based on a multipoint interferometer, has its most important application in measuring the orbital angular momentum of light from astronomical sources, opening the way to interesting new astrophysics.
