  • Chaibi, A; Mafusire, C; Forbes, A (IOP Publishing, 2013-09)
    The orbital angular momentum of light has been suggested as a means of information transfer over free-space, yet the detected optical vortex is known to be sensitive to perturbation. Such effects have been studied ...
  • Mafusire, C (SAIP 2010, 2010-09)
    A model is used to calculate the beam quality factor of a laser beam from Zernike coefficients. It is tested by programming aberration coefficients on a laser beam and measuring the beam quality using a Shack-Hartmann ...
  • Mafusire, C; Forbes, A (AOSIS OpenJournals, 2013-11)
    When the walls of an open-ended horizontal steel pipe are heated before the pipe is rotated along its axis, the exchange of the expelled heated air with the incoming cooler air, sucked in along the axis, results in a medium ...
  • Mafusire, C; Forbes, A; Snedden, Glen C; Michaelis, MM (Academy of Science of South Africa, 2008)
    The graded index (GRIN-like) medium generated by gas inside a heated steel pipe when rotated about its longitudinal axis has the ability to focus a laser beam. While the effective focal length of such a system has previously ...
  • Mafusire, C; Forbes, A; Michaelis, MM; Snedden, Glen C (2009-06)
    The graded index (GRIN-like) medium generated by a gas inside a heated pipe when it is rotated about its longitudinal axis has the ability to focus a laser beam. However, recent research has shown that the medium generated ...
  • Mredlana, Prince; Naidoo, Darryl; Mafusire, C; Kruger, T; Dudley, Angela; Forbes, A (2016-07)
    Optical field characterisation often requires various isolated experiments to obtain characterisation parameters, we investigate a novel approach to characterise an optical field employing a Wigner distribution function ...
