Author:Schulze, C; Dudley, Angela L; Flamm, D; Duparr, M; Forbes, ADate:Oct 2013We present a novel tool for sorting the orbital angular momentum and to determine the orbital angular momentum density of laser beams, which is based on the use of correlation filters.Read more
Author:Schulze, C; Naidoo, Darryl; Flamm, D; Schmidt, OA; Forbes, A; Duparr, MDate:Aug 2012We propose a new method to determine the wavefront of a laser beam based on modal decomposition by computer-generated holograms. The hologram is encoded with a transmission function suitable for measuring the amplitudes and phases of the modes ...Read more
