Query: Experimental generation of ring-shaped beams with random sources   We have experimentally reproduced ring shaped beams from the scattered
Laguerre-Gaussian and Bessel-Gaussian beams. A rotating ground glass plate is
used as a scattering medium and a plano convex lens collects the scattered
light to generate ring shaped beams at the Fourier plane. The obtained
experimental results are supported with the numerical results and are in good
agreement with the theoretical results proposed by Wang, Cai and Korotkova
(Opt. Exp. 17, 22366 (2009)).
