Nondiffracting Beams for Vortex Tomography


Nondiffracting Beams for Vortex Tomography

Jaroslav Rehácek et al. Opt Lett. .


We propose a reconstruction of vortex beams based on implementation of quadratic transformations in the orbital angular momentum. The information is encoded in a superposition of Bessel-like nondiffracting beams. The measurement of the angular probability distribution at different positions allows for the reconstruction of the Wigner function.
