Nondiffracting beams for vortex tomography
Published 12 May 2010 in physics.optics and quant-ph | (1005.2018v1)
Abstract: We propose a reconstruction of vortex beams based on the 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.
