Web22 Dec 2012 · Partial coherence is added because any practical source beam is partially coherent to a certain extent. Our aim is to see if such beams offer any advantages when they are used in horizontal optical communication links which is obviously dominated by turbulence. 2 Airy beam on source and receiver planes Webdiffraction－free beams，such as Bessel beams[1]and Airy beams[2]，are typical kinds of coherent beams

This implies that low-coherence beams have poor self-healing ability, but were found to be robust against the turbulence, distortion, scattering, etc. In this letter, we first prove numerically … grasstree beach accommodation
