Author:Forbes, A; Schulze, C; Ngcobo, Sandile; Flamm, D; Naidoo, Darryl; Dudley, Angela L; Duparre, MDate:Feb 2013Modal decomposition of optical fields as a concept has been in existence for many decades, yet despite its clear applications to laser beam analysis it has nevertheless remained a seldom used tool. With the commercialization of liquid crystal ...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
