All-digital wavefront sensing for structured light beams

Author: Dudley, Angela L ; Milione, G ; Alfano, RR ; Forbes, A Date: 2014 We present a new all-digital technique to extract the wavefront of a structured light beam. Our method employs non-homogeneous polarization optics together with dynamic, digital holograms written to a spatial light modulator to measure the ... Read more
Wavefront reconstruction by modal decomposition

Author: Schulze, C ; Naidoo, Darryl ; Flamm, D ; Schmidt, OA ; Forbes, A ; Duparr, M Date: Aug 2012 We 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
