Singularities are ubiquitous in nature and generate high levels of interest and activity among
scientists. At a singularity, a parameter of interest becomes indeterminate, a single point at …

This comprehensive and cohesive work includes all the relevant data to allow optical
engineers worldwide to meet present and upcoming challenges in their day-to-day …

Optical phase singularities, also called optical vortices, are known to have applications in
various branches of optics. Here the role played by optical vortices in collimation testing is …

A new and simple technique for the determination of the focal length of positive lenses and
concave spherical surfaces by Talbot interferometry is described. Results of measurements …

Self-imaging in near-field diffraction is a practical application of coherent manipulation of
matter waves in Talbot interferometry. In this work, near-field diffraction of protons by a …

We investigate the testing of collimation by Talbot interferometry with circular gratings.
Circular gratings are immune to misalignment owing to rigid body rotations in a plane …

We describe a simple method for measuring the radius of curvature by using Talbot
interferometry in a noncollimated light beam. This scheme can also be used to determine the …
