Method to measure off-axis displacements based on the analysis of the intensity distribution of a vortex beam
G. Anzolin, F. Tamburini, A. Bianchini +1
We study the properties of the Fraunhofer diffraction patterns produced by Gaussian beams crossing spiral phase plates. We show, both analytically and numerically, that off-axis di…

Optical vortices with starlight: Implications for ground-based stellar coronagraphy
F. Tamburini, G. Anzolin, G. Umbriaco +2
Using an l = 1 blazed fork-hologram at the focal plane of the Asiago 122 cm telescope, we obtained optical vortices from the stellar system Rasalgethi (alpha Herculis) and from the…
